Silicone tableware is a popular type of tableware in recent years, with its soft, durable, non-toxic and odorless characteristics that are highly favored by people. However, some people who use silicone tableware have reported that the tableware is prone to getting greasy and difficult to clean. So, today we will discuss the problem of greasy and difficult to wash silicone tableware, as well as the solutions to it.Firstly, let's take a look at the reasons why silicone tableware is greasy. Generally speaking, silicone tableware is difficult to wash and greasy because the oil stains are relatively viscous, and the surface of silicone is relatively smooth, making it difficult for the oil stains to stick on. Moreover, silicone tableware has adsorption properties. If left unwashed for a long time, a thin oil film will gradually form on the surface of the tableware, making it more difficult to clean. In addition, silicone tableware cannot use metal knives and forks. If used improperly for a long time, it can also cause scratches on the surface of the tableware, thereby affecting the cleaning effect.Now that we understand the reasons why silicone tableware is greasy and difficult to wash, let's take a look at how to solve this problem. Firstly, we need to prepare some cleaning tools, such as dishwashing sponges, dishwashing detergent, or lemon and other cleaning supplies. Then, soak the tableware in warm water and use a sponge or detergent to wipe off any stains on the surface of the tableware. If the stains are difficult to clean, you can try squeezing some lemon juice on a sponge or adding a little baking soda, and then wiping the surface of the tableware, which will have a better effect. Finally, rinse the tableware with clean water and place it in a ventilated and dry place.In addition, we can also pay attention to the following points when using silicone tableware: Firstly, do not use metal knives and forks to avoid scratching the surface of the tableware. Secondly, clean it as soon as possible after use and do not let stains adhere to the surface for a long time. Finally, do not place tableware in high temperatures or direct sunlight to avoid deformation or aging of the tableware.To sum up, the problem of greasy and difficult to wash silicone tableware is not difficult to solve. As long as we pay attention to it when using it and adopt the correct cleaning methods, we can keep the tableware clean and tidy. In addition, we can also learn more about silicone tableware to make our tableware more durable and healthy.

With the progress of science and technology and the development of society, people have been inseparable from plastic products and rubber products in their daily life. Today, I will introduce some simple methods to help you distinguish them. With the progress of science and technology and the development of society, people have been inseparable from plastic products and rubber products in their daily life. Today, I will introduce some simple methods to help you distinguish them. First, we start with the difference between plastic and rubber. Simply put, if plastic is deformed under the action of external force, it is difficult to restore to its original state, while rubber is easily restored to its original state. For example, if the rubber O-ring is stretched, it will return to its original shape immediately after loosening it. However, if the plastic product is deformed, it will not return to its original condition. In technical terms, under the action of external force, plastic deformation is plastic deformation, while rubber deformation is elastic deformation. Mainly depends on their molecular structure. The elasticity of plastics is generally less than 100%, while rubber can exceed 1,000% at most. Secondly, the production process is different. Rubber products have an additional vulcanization process. The silica gel sealing ring has an open porous structure and can absorb many substances. It is a good desiccant, adsorbent and catalyst carrier. The adsorption of silica gel is mainly physical adsorption, which can be regenerated and used repeatedly. Add acid to the alkali metal silicate (such as sodium silicate) solution to make it acidify, and then add a certain amount of electrolyte to stir to form a silicic acid gel; or add acid or Ammonium salts can also generate silica gel. Finally, plastic products may be repeatedly recycled and reused, while rubber products are not. It can only be processed into reclaimed rubber before being used again. O-rings are usually selected as large cross-section O-rings as possible. In the case of the same gap, the volume of O-rings squeezed into the gap should be less than the maximum allowable value.

How to Control Silicone Rubber Molding Line Quality EffectivelyRaw Material ControlCheck silicone hardness, purity and shelf life strictly; separate different materials to avoid mixing impurities.Stable Equipment & MoldsKeep molding temperature, pressure and curing time fixed; clean and maintain molds regularly, ensure smooth venting to avoid bubbles and flash.Standard OperationFollow unified production SOP; do first article inspection before mass production.In-process InspectionSpot check size, appearance, hardness hourly; stop production timely once defects occur.Finished Product InspectionCheck appearance, dimension and physical properties; screen out unqualified goods.Environment ManagementKeep workshop dry, dust-free and constant temperature to ensure stable product quality.

To ensure that the seal plays a positive role and avoid failure, the following points must be noted:Material compatibility: Rubber materials must be compatible with the medium they come into contact with (oil, water, chemicals, etc.), otherwise swelling, shrinkage, softening, or hardening may occur, leading to failure.Working temperature: Each rubber material has its applicable temperature range. Excessive temperature can accelerate rubber aging, become brittle, and lose elasticity; If it is too low, it will make the rubber harder and lose its sealing ability. Pressure: Seals must be able to withstand the working pressure of the system, and special sealing structures with retaining rings may be required for high-pressure conditions.Surface quality: The roughness, hardness, and flatness of the metal surface (such as shafts, holes) in contact with the seal are crucial. Rough or scratched surfaces can rapidly wear down seals, leading to early failure.Installation quality: Incorrect installation (such as using violence, not adding protective covers, and not paying attention to cleaning) is a common cause of seal damage before being put into use.

Silicone, as a widely used flexible material, many users are concerned about whether it will age during use? How long is the service life of silicone? How to maintain it for longer? In fact, any polymer material will experience performance degradation over long-term use, and silicone is no exception. However, the aging rate of silicone is much slower than that of materials such as rubber and plastic. This article will provide a detailed explanation of the aging reasons, service life, and scientific maintenance methods of silicone, helping everyone to extend the use time of silicone products. Silicone does experience aging, but the aging rate is very slow. The service life of silicone products in ordinary environments can usually reach 5 to 10 years, and high-quality food grade and industrial grade silicone can even be used for more than 10 years. The aging of silicone mainly manifests as surface hardening, cracking, yellowing, loss of elasticity, decreased sealing, etc. The reasons for aging mainly include long-term high temperature exposure, ultraviolet exposure, acid-base corrosion, oil contamination contact, oxidation reaction, and long-term repeated bending and extrusion. Among them, ultraviolet radiation and high temperature are the main factors accelerating the aging of silicone gel. Long term use in direct sunlight outdoors will significantly shorten the lifespan of silicone gel. The lifespan of silicone varies greatly in different usage environments. Silicone products used in indoor dark, room temperature, and dry environments, such as silicone kitchenware, silicone tableware, silicone gaskets, etc., can almost maintain long-term stability and age extremely slowly. Silicone products that are used in outdoor, high-temperature, sun exposed, and humid environments for a long time, such as silicone hoses, silicone sealing strips, outdoor silicone accessories, etc., will age relatively faster, but are still much more durable than other materials. Medical silica gel and food grade silica gel have stronger anti-aging ability because of their high purity and less additives.The correct maintenance method is crucial for delaying the aging of silicone and extending its service life. Firstly, it is necessary to avoid prolonged direct sunlight and high temperature baking. Silicone products should be placed in a cool, dry, and ventilated place as much as possible, and should not be near heat sources, open flames, or exposed areas. Secondly, it is advisable to minimize long-term contact between silicone gel and strong acid-base, chemical solvents, engine oil, diesel and other media to avoid corrosion of the surface structure and performance degradation. When cleaning, use clean water or neutral detergent, do not use highly corrosive disinfectants, air dry naturally after cleaning, and do not dry or expose to high temperatures.In addition, avoiding silicone products from being excessively stretched, squeezed, or folded for a long time and maintaining their natural shape can effectively reduce internal structural fatigue and delay aging. For industrial silicone accessories such as seals, hoses, gaskets, etc., the surface condition should be regularly inspected. If obvious hardening, cracks, or deformation occur, they should be replaced in a timely manner to avoid affecting equipment operation. Household silicone kitchenware should avoid being scratched by sharp objects, maintain surface integrity, and also improve durability. In summary, silicone will age, but at a slow pace and with a long lifespan, it can be used normally for several years or even over a decade. By understanding the causes of aging and adopting maintenance methods that avoid light, high temperatures, corrosion, and proper cleaning, the service life of silicone products can be significantly extended.

In order to improve the cold resistance of rubber materials, researchers have adopted various methods. These methods mainly include rubber copolymerization and chemical modification, rubber blending, addition of plasticizers, rational selection of vulcanization and filling systems, etc.1. Rubber copolymerization and chemical modification Rubber copolymerization and chemical modification are effective methods to improve the cold resistance of rubber materials. By introducing monomers with large side groups for copolymerization, the regularity of rubber molecular chains can be disrupted, and their Tg and Tb can be reduced. For example, introducing monomers with flexible structures into fluororubber molecules can increase the flexibility of the molecular chains, reduce intermolecular forces, and thus improve the cold resistance of fluororubber. In addition, chemical modification methods such as epoxidation and isomerization can be used to alter the structure of rubber molecular chains and improve their cold resistance.2. Rubber blending is a common method to adjust cold resistance in rubber formula design. By combining different types of rubber, their respective advantages can be comprehensively utilized to improve the cold resistance of rubber materials. For example, combining styrene butadiene rubber (SBR) with butadiene rubber (BR) can improve the cold resistance of the rubber. This is because SBR and BR have lower Tg and good molecular chain flexibility, and can still maintain a certain degree of elasticity at low temperatures.3. Adding plasticizers is one of the effective measures to improve the cold resistance of rubber materials. Plasticizers can increase the flexibility of rubber molecular chains, reduce intermolecular forces, and make molecular segments easier to move. At low temperatures, plasticizers can act as lubricants, reducing friction and resistance between rubber molecular chains, thereby improving the cold resistance of rubber. Common plasticizers include petroleum based hydrocarbon solvent plasticizers and non solvent plasticizers.

Prevent nails from being scratched or damaged by prolonged contact with buttons, and protect the screen and buttons;4. The anti slip function; And the tactile quality is very good;5. Protect your phone from accidental drops to prevent damage. production processSilicone sleeve is a silicone product produced by high-temperature molding and vulcanization process using silicone as the main raw material.Ordinary silicone sleeves need to go through the following processes:1. Raw material preparation (also known as rubber mixing): including the mixing of raw rubber, color blending, etc;2. Sulfurization molding (also known as hydraulic molding): High pressure hydraulic press is used for high-temperature vulcanization to solidify the silicone collagen material into a solid state;3.

Screen printing, this process is only used for some silicone sleeve products with patterns or logos on the surface of the silicone sleeve;5. Spray oil, silicone products are easy to adsorb dust in the air and have a certain viscosity; Spray hand feel oil on the surface of the silicone sleeve, which can prevent dust and enhance the hand feel;6. Other, including providing additional functions such as dispensing glue, laser engraving, or assembling other materials and components.

From the perspective of current technology, the sealing and protection technology of many products still has certain defects in the actual process, such as waterproof sealing of our mobile phones, waterproof sealing rings of automotive lighting fixtures, etc. The use of silicone and rubber materials as sealing materials is the most common type of material. Therefore, silicone sealing rings, as a type of sealing component used in various aspects, often encounter unexpected functional problems during normal use and cannot demonstrate the effectiveness of the product. So, what are the considerable factors that affect it? Influence of hardness and softnessMany times, the different softness of silicone products can completely change the functionality and structure of the product. Therefore, due to the selection of silicone sealing rings with different hardness and softness, unavoidable problems may occur during use, such as extrusion gaps, excessive stress, high hardness, product deformation without rebound, and other factors. Gap issueThe gap problem can be divided into several factors. Firstly, it is due to the material of the rubber material. Many silicone materials have poor rebound force and insufficient tensile force due to the formula, resulting in insufficient force during use and leakage due to gaps. Processing problems of silicone ring manufacturers, such as making the product brittle and resulting in thin edge thickness, are prone to this problem. Making the product soft can cause the rubber material to have internal bulges and become immature, and long-term stretching and compression can cause deformation and gap problems. Force processO-type silicone rings are generally installed in several places, such as grooves, flat surfaces, and convex grooves. The installation method of each product is different, and its stress process will also affect the service life and function of the product. Therefore, in order to ensure the sealing performance, a reserved space is made for this storage. The different methods and stress levels of silicone rubber sealing rings are distinguished, such as how much they can withstand in flat installation and how tight they are when adjusted, and how much stress they can withstand in concave and convex surfaces, and how much size is reserved. Compress permanentlyAnother indicator for evaluating the sealing performance of O-rings is the compression permanent cross shape of the selected material. Under pressure, the O-ring as an elastic element undergoes elastic deformation, and permanent plastic deformation also occurs as the pressure increases. Usually, to prevent permanent plastic deformation, the maximum allowable compression of O-rings is about 30% in static seals and about 20% in dynamic seals. When installing silicone sealing rings in grooves, they should be subjected to tension or compression. If the values of stretching and compression are too large, it will cause an excessive increase or decrease in the cross-section of the O-ring, as stretching by 1% will reduce the diameter of the cross-section by about 0.5%. For hole seals, the O-ring is in a stretched state, allowing a tensile force of 6%. For shaft seals, the O-ring is best compressed along its circumference, allowing a circumference compression of 3%.

For silicone products (phone cases, kitchen tools, keypads), making a clear, durable logo font only requires two steps: proper font preparation and choosing a suitable processing method. This article explains it simply. Part 1: How to Make the Logo Font (Simple Preparation) No professional design skills are needed; focus on 3 key points for a clear, non-deformable font. 1. Choose simple sans-serif fonts (e.g., Arial, Helvetica) instead of fancy script/serif ones—they are clear and wear-resistant even for small logos. 2. Keep font stroke ≥0.3mm (thinner strokes break easily) and size matching the product to ensure readability. 3. Prepare vector files (AI, PDF, SVG) for the font; avoid blurry pictures (e.g., JPG) as they are the basis for processing. Part 2: Common Processing Methods (Simple Explanation + How to Choose) 6 common methods, focusing on pros, cons and suitable scenarios for easy selection. 1. Mold Emboss/Deboss (Most Common for Mass Production) Carve the logo on the mold; the logo forms with silicone vulcanization (emboss = raised, deboss = recessed). Pros: No extra cost after mold making, wear-proof, 3D touch. Cons: Same color as silicone, unchangeable once mold is made. Suitable for: Mass-produced products with simple logos (kitchenware, tool handles). 2. Screen Printing (Cheapest for Flat Surfaces) Scrape ink through a stencil onto flat silicone surfaces and dry. Pros: Low cost, bold colors, clear edges, suitable for large logos. Cons: Only for flat surfaces, surface ink wears off easily. Suitable for: Low-friction flat products (silicone mats, simple phone cases). 3. Pad Printing (Best for Curved Surfaces) Use a soft silicone pad to transfer logo ink to curved/uneven surfaces. Pros: Fits curved surfaces, supports multi-color small logos. Cons: Higher cost than screen printing, average ink durability. Suitable for: Curved products (silicone buttons, curved phone cases). 4. Laser Engraving (Most Durable for High-Use Products) Spray a base color, then laser off the top layer to reveal the logo. Pros: Extremely wear-proof, smooth surface, suitable for backlit products. Cons: Single-color only, high equipment cost, needs translucent silicone. Suitable for: High-wear/backlit products (automotive controls, medical keypads). 5. Drip Ink (Most High-End for Heavy-Use) Fill mold recesses with ink, cure to embed the 3D logo in silicone. Pros: Indestructible, strong 3D sense, high-grade. Cons: Slow process, high cost, simple fonts only. Suitable for: High-end heavy-use products (industrial keypads, luxury accessories). 6. UV/Digital Printing (Best for Full-Color Logos) Print directly with UV ink, cured instantly by UV light. Pros: Full-color complex logos, no stencils needed, suitable for small batches. Cons: Higher cost, average durability, not for frequent friction. Suitable for: Premium products with complex logos (custom gifts, high-end phone cases).

Many people who have come into contact with silicone products know that some silicone products are prone to sticking to dust. So why do silicone products prefer to stick to dust? I believe friends who have used silicone products will have this question, especially the commonly seen silicone phone cases, silicone wallets, etc. in our daily lives, which are often prone to dust and difficult to clean. So, what are the reasons why silicone products stick to dust? In fact, the adsorption force of silicone products is a constant characteristic of silicone materials. Most silicone products have some dust adsorption function, but some silicone products undergo special processes before leaving the factory to make them non stick to dust. For example, in the production of silicone products, they generally need to be treated with oil spray. After the oil spray treatment, silicone sleeves and other silicone products will not be dusty, even if accidentally dropped on the ground, they will not easily get dusty. Therefore, when purchasing some consumer goods, you can choose some silicone products that have been treated with oil spray, so that they have a good grade in terms of feel and texture. Industrial accessories or electronic accessories are simple silicone products. There's no need to be so particular, So everyone still needs to refer to it when selecting silicone products.
