Everyone knows that silicone products are no longer as monotonous as before. Many accessories in the market, kitchen supplies in daily life, household items, and so on have different colors. However, many purchasing friends have doubts about the colorful silicone products, fearing that their color quality may have various problems. But for friends who are not very familiar with silicone products, do you know how silicone products are colored?   Silicone raw materials are originally transparent in color, colorless and odorless. They are a highly active material with strong adsorption properties and do not conflict with any substances except for strong alkalis. However, due to the need to maintain various styles of silicone raw materials during the production process, there are many choices available. Therefore, silicone product manufacturers use colorants to add various colors to it to maintain its appearance. Silicone colorants are formed by the aggregation of silicone raw materials, silicone oil, color powder, and dispersants. Therefore, choosing to use silicone colorants to produce the color of silicone products is because of their stable performance, high dispersibility, uniform use on products, environmental protection, non toxicity, non pollution, long-term storage, and will not expire. Many characteristics are similar to those of silicone raw materials. It can also be divided into many types, mainly organic colorants and inorganic colorants.   Silicone color masterbatch is an indispensable item for silicone product manufacturers. Its main process is used in the rubber mixing process. If no color masterbatch is added during the rubber mixing process, the mixed rubber will be transparent color. After molding and vulcanization, transparent silicone products will be obtained. The color of silicone masterbatch needs to be carefully adjusted to achieve good results, which is also an important technical task for silicone manufacturers. The color can reach thousands of different colors, and many products with little color difference are the most difficult to adjust. And when it is made with silicone raw materials, it is distributed according to the corresponding proportion and combined with vulcanizing agents to obtain the raw materials for making products. The performance selection of color masterbatch also affects the performance of a product. The common reason for color change in silicone products also has certain reasons in the selection of color masterbatch. The choice of light resistance performance, strong light resistance can achieve no color change effect, generally divided into eight levels! Heat resistance, the better its heat resistance, the higher its dispersibility. A high dispersibility means that the color distribution of the product is uniform, so it can be chosen in any way.

What is laser engraving technology? How to apply it in the silicone rubber products industry? Many people may not understand it very well! Laser engraving or laser marking, laser engraving is a surface treatment process similar to mesh transfer printing, which involves printing characters or patterns on products. Laser engraving, also known as laser engraving, is a process that uses optical principles for surface treatment. It is commonly used for buttons on mobile phones and electronic dictionaries. Make permanent marks on the surface of a substance or inside a transparent substance using a laser beam. Laser has two types of effects on matter: chemical and physical effects. When a substance absorbs laser in an instant, a physical or chemical reaction occurs, resulting in the engraving or display of patterns or text. Therefore, it is also known as a laser marking machine or laser engraving machine!

For consumers who are not familiar with silicone materials, the physical hardness of silicone rubber products may cause great inconvenience. The same product size will not have much variation, and the relationship between material formulation and various physical properties is not fully understood, which can lead to many functional impacts on assembly. Various raw materials such as silicone and rubber have their own hardness and flexibility characteristics, and silicone rubber products are no exception. So why silicone materials can be used in various industries is because they have different soft and hard supports!   Different silicone products have their unique properties and process requirements. For example, silicone seals, silicone accessories, etc., the most suitable polymer and combination can be selected and reasonably adjusted to achieve a tight fit of softness and hardness. Sealing, shock absorption, waterproofing, oil resistance, etc. The physical properties of softness and hardness are closely related to the formula and raw materials of the product. The debugging of formulas can test various performance differences and functions, so it is still necessary to debug the softness and hardness, otherwise the error in softness and hardness may inevitably cause trouble! Everyone knows that silicone materials have good tensile strength, and the indicator of tensile strength depends on the softness and hardness of the product. The general softness and hardness of silicone rubber product manufacturers are around 20-80 degrees. The lower the hardness, the better the product. The tensile strength is good, generally reaching around 300%, with the lowest being around 20%. However, the tensile strength still depends on the structure and shape of the product.   What silicone materials cannot do without is tear strength. Silicone rubber materials can tear due to stress factors. This is one of the inevitable phenomena in all soft colloidal materials, where cracks and fissures can cause damage due to stress. It accounts for a minority because normal hardness silicone rubber generally does not tear or break. Materials with higher hardness are prone to tearing due to crack propagation! Therefore, the tensile strength and hardness of silicone products are important indicators of the material. In the vulcanization production process of silicone processing manufacturers, the larger the silicon molecular weight of the mixed rubber, the greater the effective cross-linking elongation stress. In order to obtain the specified tensile stress, for materials with smaller molecular weights, the crosslinking density can be appropriately increased. Any structural factor that can increase intermolecular forces. Increasing the density of silicone material can prevent the hardness of the product from affecting its tensile strength!

Sealing plugs are usually made of silicone rubber soft gel, and many common items in daily life cannot do without the assistance of silicone sealing plugs. Whether its functionality can meet the sealing performance of the product body and the long-term service life performance depends on whether its quality can meet your usage performance!   The function of silicone sealing plugs mainly includes several sealing forms for mouth sealing, such as conical inner buckle sealing type, outer sleeve buckle sealing type, internal reverse buckle sealing, thread twist sealing, I-shaped concave convex sealing, etc. Each sealing effect depends on the main structure of the product. In addition to the structure, it is necessary to understand several basic points to determine its sealing effect and use digital technology. 1. The material factor plays a significant role. Firstly, the performance of the material affects its tensile rebound deformation rate. Due to different formulations and the formulation of silicone source manufacturers, the properties of the raw materials used are different. Silicone materials also have specific properties, such as which material is suitable for functional seals and which is suitable for appearance parts, which have certain differences. So the selection of materials must have specific formula properties. Secondly, the hardness of the material is crucial, and different levels of softness and hardness are one of the main issues that lead to the sealing assembly of silicone plugs. For example, 30 degrees and 80 degrees are two different concepts. Their difference lies in the fact that 30 degrees of softness can be used for better airtightness and liquid sealing performance, while 80 degrees of high hardness can better cushion stress performance. Therefore, both types of hardness have their own advantages and are used in different ways for mechanical equipment and household sealing.   2. The softness and hardness caused by processing are different, and sealing plugs can easily lead to two different phenomena during the production process. During the production process, due to the increase in production and the acceleration of vulcanization speed, the product may become soft and partially immature, resulting in assembly softening. Secondly, the processing time is too long and the mold cannot be released in time, resulting in long-term high-temperature curing and brittleness.   3. Whether the structure of the design is reasonable, as silicone belongs to soft colloids, if used for a long time, there is no certain interference difference in the design. Long term friction can easily cause the sealing plug to fall off and loosen. Therefore, in the design, it is necessary to grasp the size of the silicone sealing plug as much as possible, and at the same time adjust the soft hardness with the size. When increasing the hardness, the interference amount needs to be reduced, and when the hardness decreases, the interference amount must be increased to ensure the tightness of the plug. To ensure the sealing performance of the sealing plug, the above methods can be used as a reference for general methods. However, for some special sealing plugs, it is recommended to adjust them before conducting sample experiments to ensure their safety performance before mass production.

Why can silicone products adapt to various scenarios? In the morning, the kitchen is filled with the aroma of bread, and silicone dough pads support the rise and fall of dough; In the afternoon gym, anti slip handles assist in iron lifting training; At the desk at night, the keyboard wrist rest relieves typing fatigue - silicone products are shuttling through different scenes with amazing adaptability. This polymer material composed of silicon oxygen bonds, with its unique physical and chemical properties, has found a perfect balance between rigidity and flexibility, becoming a practical solution that spans multiple fields.   The molecular structure of silicone endows it with excellent environmental adaptability. The main chain formed by the alternating arrangement of silicon atoms and oxygen atoms is like a precisely designed spring system, which can withstand both high temperature roasting and low temperature freezing. The baker adjusts the temperature of the chocolate to 45 ℃ and injects it into a silicone mold. After cooling, it can be easily demolded; The silicone water bottle carried by mountaineers is still flexible and usable in extremely cold environments of minus 30 ℃. Laboratory tests have shown that high-quality silicone can withstand tens of thousands of stretches without deformation, which is the key to the durability of products such as sports protective gear and phone cases.   The tactile experience is the core competitive advantage of silicone compared to traditional materials. The dense microstructure on its surface produces a delicate touch similar to that of skin, and baby teething gel uses this skin friendly property to alleviate discomfort during teething. Medical device designers apply a protective layer that fits the curve of the human body around the prosthetic socket by adjusting the hardness of silicone, reducing friction pain and improving wearing comfort. This precise control over the tactile dimension allows silicone to surpass ordinary industrial materials and become an emotional carrier for transmitting temperature.   The emergence of food grade silicone has reconstructed the art of cooking. The adhesion problem that is difficult to solve with traditional metal baking pans can be easily solved with silicone molds. The French macaron is able to fully present its iconic skirt edge due to the elasticity of the silicone mold; The homemade yogurt maker utilizes the thermal conductivity uniformity of the silicone inner liner to ensure that every spoonful has a smooth texture. What is even more commendable is that the nanoscale gaps between silicone molecules can accommodate the penetration of cleaning agents without leaving any food odor, completely solving the problem of dyeing dark sauces.   The medical and health field witnesses the safety boundary of silicone. The artificial joint implant uses medical grade silicone to cushion bone friction; The hearing aid catheter is made of biocompatible silicone material, which ensures the efficiency of sound wave transmission and reduces the risk of allergies. Behind these applications is the strict certification of platinum catalytic molding process by international standards, ensuring that the material purity reaches medical grade.   When night falls, the office keyboard wrist support lifts the tired wrist, and the diving mirror sealing ring blocks seawater intrusion. Silicone participates in the narrative of modern life in its unique way, serving as both a tool for solving problems and a detail for improving quality. From micro level molecular design to macro level usage scenarios, this synthetic material is writing its own footnote to the era - not a disruptive technological revolution, but a silent practical wisdom. Perhaps one day when we take inventory of our home items, we will find that those silicone products that silently serve have already become an important cornerstone of living comfort.

Although 30 ° silicone and 70 ° silicone can also be used with 55 ° silicone, it is still not recommended to mix them together. This is because mixing these two types of rubber together not only makes the rubber extremely sticky to the rollers, but also makes it difficult to demold during hydraulic molding, especially for silicone buttons with complex structures in silicone products. The hardness of silicone buttons is determined by the silicone raw material, with common silicone hardness levels of 30, 50, and 70 degrees. As the hardness of silicone buttons increases, their tactile feel improves. However, if the hardness is too high, it can also affect the product's service life. The lower the hardness, the softer the corresponding Keypad of the silicone button will be, resulting in a poorer tactile feel. Additionally, the friction between the Key and the plastic hole will increase, which can easily cause key jamming. Therefore, making silicone buttons generally requires a silicone hardness of 50 ° or 60 °. I'm not very familiar with the hardness of silicone buttons, right! Below we will explain in detail the common hardness of silicone buttons. Just like how we need to mix 55 degree 10KG weight silicone, using 50 ° and 70 ° silicone, according to the formula, the weight distribution of 2.5KG of 70 ° silicone and 7.5KG of 50 ° silicone can produce 55 ° silicone. The same principle applies to other degrees of silicone. When the customer requests customized silicone buttons with a hardness that is not on the commonly used silicone hardness values, the hardness needs to be adjusted according to the customer's requirements. Specific allocation formula: (Target hardness degree - Low hardness degree) ÷ (High hardness degree - Low hardness degree) x Required weight=Weight of high hardness rubber material Required weight - weight of high hardness rubber material=weight of low hardness rubber material

As a silicone material, it is also appropriate to apply it to watch straps and bracelets, which has gradually made many silicone wearable accessories popular. However, in this market situation, different qualities and brands make it difficult for many people to choose. When purchasing silicone smart bracelets, they do not know how to judge. So, have you researched the material before purchasing? In terms of electronics, current smart watch straps are not as good as mobile phones. Simple step counting, sleep monitoring, and waterproofing are standard features, while functions such as answering and making calls, using headphones, and positioning have been upgraded to a higher level. However, with the advancement of technology, these functions are not much different. The main problem with the intermediate electronic components in terms of materials is that the lithium battery and circuit board, LED, OLED panel, etc. are basically the same, and there will not be too many problems. The main issues are still assembly and watch strap. Smart wristbands are different from mobile phones in that they come into long-term contact with the skin, so the material cannot cause allergies in the human body. Therefore, many materials are not suitable for them. Comfort, durability, and stain resistance are also important indicators for wristband material selection and design. Silicone material is currently the closest type of material to safety and environmental protection, so choosing it is not suitable. However, silicone products also have certain problems before proper handling and processing, such as oil intolerance, dust adhesion, and adhesive odor. Therefore, before purchasing, you need to pay attention to the following issues: 1. Surface smoothness: Silicone products also have strong adsorption force after processing, so there may be dust sticking, poor smoothness or inconsistent surface during production. If the smoothness is not good enough and there is dust sticking, then the product has not been treated with oil spraying, or the mold of the silicone strap manufacturer has rough workmanship and surface treatment. Usually, watch straps are sprayed with hand feel oil to maintain a smooth hand feel. 2. Stretch rebound. The service life of silicone wrist straps depends entirely on the material quality of the product, that is, the stretch elasticity. If the product does not have good rebound and extension force, it proves that the product is only made of ordinary or low-quality materials. Therefore, if the purchased product has natural fracture under non-human conditions, it is necessary to find the source material problem. 3. Appearance color and aesthetics are the most important factors. The high-quality surface effect of a product determines its return rate, so it is naturally best to have no defects. However, silicone bracelets have their own shortcomings, mainly due to the parting lines and appearance color effects of the product. There is basically no cross color, mixed color, or dark mark phenomenon in color, and parting lines are inevitable, only the thickness is different. The finer the parting lines, the higher the quality and effect. So there are still certain skills and methods for choosing silicone smart bracelets. Overall, although silicone smart bracelets are mostly used, there are basically no major problems in normal use, and human damage still accounts for the majority. Therefore, silicone wristbands should be avoided from being sharp or burned.

How to distinguish the hardness and softness of silicone materials in silicone products? In many product design and development processes, it is impossible to predict how soft and hard materials are needed to achieve functionality. Therefore, how should the hardness and softness of silicone products be selected?   For silicone materials, hardness determines whether the assembly function of the main product can be achieved and whether the buffering and shock-absorbing effect can be achieved. Currently, the hardness of silicone products commonly ranges from 20 ° to 80 ° in different industries. However, with the development and progress of materials in recent years, it can now reach 90 °. Under normal circumstances, the tolerance range of hardness is ± 5 °, and manufacturers of finer grained raw materials can also adjust it to ± 2 °. For some products, the accuracy of hardness mainly determines the functional role of the product. However, currently, the common hardness of mixed rubber products is mainly between 40-60. Compared to metal materials, silicone is different, so the tolerance range for both hardness and product precision is relatively large. Silicone accessory manufacturers must have put in enough effort to strictly control the hardness and dimensional tolerance of the silicone products they produce. For high hardness silicone products, the higher the hardness of the product, the more brittle it becomes, and the tear resistance will increase. The self splitting mold line and burrs are easily brittle, so the structure is one of the most critical issues. If the structure is complex, even if there are inverted or right angle products after processing, improper use can easily lead to damage. Therefore, the higher the hardness, the simpler the structure of the product. The production yield and service life rate of overly complex products will be lower. For low hardness silicone products, the opposite is true. Products with lower hardness can have more complex structures and are easier to produce and process, resulting in better elasticity. However, the same tearing resistance may cause fracture during stretching, which is also related to the raw materials. However, silicone product manufacturers are prone to softening and undercooking of low hardness products during processing, and may also cause fracture due to oblique or right angles under normal force. Silicone products with different hardness have different functional effects, and the difference in hardness and softness is mainly used as the functional effect of the product. Generally, a hardness of 30 ° -70 ° can achieve the best functional effect of the product. If the hardness is too low or too high, it may cause some products to be difficult to process, increase the cost and production efficiency of the product.

What are the raw materials for silicone products? Silicone products have been widely used in various fields such as daily life, medical care, and industry due to their unique physical and chemical properties. From baby pacifiers to kitchen utensils, from medical catheters to electronic seals, silicone products are everywhere.   1. Core raw material for silicone products: silicone rubber The main raw material for silicone products is silicone rubber, which is a polymer elastomer formed by alternating silicon and oxygen atoms. Silicone rubber has excellent high and low temperature resistance (can be used for a long time within the range of -60 ℃ to 250 ℃), aging resistance, chemical corrosion resistance, and good biocompatibility. According to the different vulcanization temperatures and vulcanization mechanisms, silicone rubber can be divided into two categories: high-temperature vulcanized silicone rubber (HTV) and room temperature vulcanized silicone rubber (RTV), which are suitable for different processes and application scenarios. 2. Auxiliary raw materials for silicone products: fillers and additives In addition to the silicone rubber matrix, various fillers and additives need to be added during the production process of silicone products to improve performance. Common fillers include white carbon black (silica), which can enhance the strength, hardness, and wear resistance of silica gel; Calcium carbonate is used to reduce costs and regulate hardness. In terms of additives, vulcanizing agents are the key to promoting cross-linking and curing of silicone rubber, while coloring agents, flame retardants, anti-static agents, etc. are used to endow silicone products with specific functions such as color, fire resistance, or anti-static properties. 3. Production process of silicone products: molding and extrusion The production of silicone products mainly adopts two processes: compression molding and extrusion molding. Compression molding is the process of placing pre mixed silicone rubber raw materials into molds and vulcanizing them through high temperature and high pressure. It is suitable for products with complex structures and high precision requirements, such as sealing rings, buttons, etc. Extrusion molding is the process of heating and plasticizing silicone rubber raw materials through an extruder, extruding them into continuous profiles through a mold, and then vulcanizing them to obtain the final product. It is commonly used in the production of pipes, strip seals, etc. Both processes have their own advantages and can be flexibly selected according to product requirements. 4. Performance advantages and application areas of silicone products Silicone products have shown broad application prospects in multiple fields due to their unique performance advantages. Its excellent resistance to high and low temperatures makes it an ideal material for fields such as aerospace and automotive electronics; Good biocompatibility and non-toxic properties make it widely used in the medical field, such as making catheters, artificial organs, etc; In addition, silicone products have the characteristics of easy cleaning, aging resistance, and rich color, and are widely used in kitchen utensils, baby products, toys, and other fields, bringing convenience and safety to people's lives.

In daily life, I believe everyone is familiar with acrylic sheets. Some people may think that acrylic is a new material that has only emerged in recent years, but in fact, the research and development of acrylic has a history of more than 100 years and is known as the "plastic queen". Acrylic sheets are now widely used in various fields of civilian products, but do you truly understand acrylic? Next, the editor will take you into the colorful world of acrylic to get to know it together.   What is acrylic sheet? The Chinese name for acrylic is transliterated from the English word Acrylics, and the common Chinese names are acrylic and acrylic. It is a general term for acrylic and methyl acrylic chemicals. Including monomers, boards, granules, resins, and composite materials. Acrylic sheet is polymerized from methyl methacrylate monomer (MMA), also known as polymethyl methacrylate (PMMA) sheet organic glass, which is a special processed organic glass.   Performance characteristics of acrylic: 1. Lightweight, acrylic is a relatively lightweight material with a density of only 1.19-1.20, about half of ordinary glass and 43% of aluminum metal. 2. It has good flame resistance, will not self ignite and can self extinguish. 3. It has excellent electrical insulation properties and is a highly suitable high-frequency insulation material for the wireless instrument industry. 4. It has good transparency, with a transmittance of over 92%, which is more than 10% higher than ordinary glass, and has a crystal like texture and luster. 5. Not afraid of moisture, water, mold, bacteria, and corrosion. 6. The impact resistance is sixteen times that of ordinary glass, with almost no risk of breakage.   Is acrylic board PVC? Acrylic and PVC are two completely different materials, and PVC board is a honeycomb shaped mesh structure board made of PVC as raw material. It is a vacuum formed film used for surface packaging of various panels, also known as decorative film or adhesive film, and is applied in many industries such as building materials, packaging, and medicine. The above content introduction is about acrylic. Acrylic and PVC are two different materials, so acrylic is not PVC.
