Conductive silicone rubber usually means that the volume resistance is within 10 to the 9th power of ohm cm. Conductive rubber is divided into anti-static conductive rubber.   1.The surface resistance of antistatic silicone rubber products reaches 10 to the power of 5-12, which is an antistatic level. Within the 9th power of 10, the 6-8th power of 10 is permanent, but the performance of the raw material will deteriorate, and the 9th power of 10 is short-term antistatic. 2.The surface resistance of conductive silicone rubber products is less than 10 to the 5th power, which is the conductive level. The volume resistivity is generally 3-10Ω·cm, the relative density is 1.15, the hardness (Shore A) is 60, the tensile strength is 5.7MPa, and the relative elongation is 265%. It can be mixed and mixed with methyl vinyl silicone rubber (raw rubber), white carbon black, conductive filler, structure control agent and organic peroxide. When the volume resistance is less than 10 ohm cm, the conductive rubber has electromagnetic shielding function.   Many silicone products are used in electronic and electrical components, which must be antistatic. Antistatic agents can be added when producing silicone products.  

Silicone rubber buttons are widely used in color TV sets, air conditioners, calculators and electronic game consoles. Screen printing quality directly affects the quality of the product appearance. 1. Key mold production Qualified mold not only to achieve the technical indicators of the keys, but also to meet the requirements of screen printing. Ensure that the key surface surface finish is high, only the smooth surface can print the character edge clear and three-dimensional words. Conversely, the rough surface printed characters must be uneven surface, the edge of the burr. The best screen printing effect is based on good mold. 2. Silicone rubber formula The raw material formula of the silicon rubber key sheet that needs screen printing must strictly control the content of release agent, not only consider the release convenience but ignore the screen printing binding force. Release agent content is too high, printing after drying, gently wipe off. Demoulding agent is too high, transparent or white key pieces by printing drying will cause yellow phenomenon, seriously affect the appearance of the product quality. 3. Drying temperature Post-press drying temperature is too high, often make light color and white key pieces yellow phenomenon, too low temperature will cause poor binding force. Therefore, strict control of temperature is one of the keys to ensure the binding force of printing. Drying products must be cooled before they can be loaded into the turnover box, otherwise light or white products will be yellow and affect the appearance.

The structure of PU resin influences the material's ethanol resistance, and the solid particles are optimized to obtain the PU coating for high-performance silicone rubber keys, as shown below:   1. Resin structure affects the ethanol resistance of the coating, and hydroxyl acrylate is more resistant to ethanol than hydroxyl polyester; At the same time, the resin with high hydroxyl value and glass transition temperature has higher ethanol resistance.   2. The solid particle filler with small particle size can effectively fill the internal void of the coating, which is manifested as improved ethanol resistance. With the increase of solid particle size, the ethanol resistance of the coating decreases rapidly.   3. Compared with the existing PU wear-resistant coating, the ethanol resistance of the improved PU coating is improved, which is better in ethanol resistance and RCA performance, meeting customer requirements.

Does mixed silicone rubber burn easily?Some friends usually ask this question before purchasing. Today we will find out whether mixed silicone rubber is inflammable. The mixed silicone rubber is made of raw rubber, silica, silicone oil and other auxiliary materials mixed at high temperature. It is safe, environmental friendly, non-toxic, tasteless and resistant to high and low temperature.The mixed silicone rubber can be stored for a long time at room temperature. The surface of the rubber will become yellow and crack under high temperature irradiation, and it is not inflammable. The only flammable phenomenon of mixed silicone rubber is that when adding odorless vulcanizing agent, the static electricity generated by the constant friction between the rubber and the cylinder will directly react with the vulcanizing agent, which may lead to the ignition phenomenon. When adding vulcanizing agent, we can reduce the speed of the roller of the refining machine, or we can gradually add the vulcanizing agent in a small dose. In addition, mixed silicone rubber can also be added additives to make flame retardant silica gel, even in the state of open fire can be made completely non-combustion, flame retardant silica gel is mainly used in industrial equipment production and manufacturing links.

The report said 82 per cent of Gen Z Singapore consumers surveyed said they had tried "cashless shopping", up from 74 per cent of Gen Y (born between 1980 and 1995) consumers. Digital payments are profoundly affecting and changing the way young Singaporeans shop. Seventy percent of Gen Z respondents said they would be willing to go to a store with a self-checkout device, with another 70 percent of those willing to accept biometric payments. The study found that about 60 per cent of Singapore consumers have tried "cashless shopping" for reasons including faster speed and efficiency (47 per cent), convenience (47 per cent) and ease of tracking and tracing financial records (43 per cent). The type of cashless transaction singaporeans were most likely to make was to pay bills, at 62 per cent. Another 59 percent and 56 percent said they would go cashless for public transportation-related transactions, as well as taxi rides and ride-sharing payments. The Visa survey found that 74 per cent of Singaporean consumers are using contactless cards, with another 84 per cent using them at least once a week. Other digital payment methods widely used locally include online card payments (81 percent), mobile contactless payments (49 percent) and swiping/inserting payments (48 percent). About 80 percent of Singaporean employees aged 18 to 24 would be willing to work remotely overseas, according to a 2021 survey by Randstad, a leading global staffing company. Only half of workers aged 55 to 67 expressed interest in working remotely overseas. Chaya Das, managing director of Randstad Singapore, said that the younger generation prefers remote working to older ones mainly because they have grown up in a global environment and are open to the opportunities and challenges of intercultural communication.

Silicone rubber has excellent elasticity and high and low temperature resistance, and is widely used as sealing material in the aerospace field. With the development of aerospace engineering, the problem of silicone rubber sealing is gradually prominent, so it is of great significance to the preparation and performance research of silicone rubber sealing material. Taking methyl vinyl silicone rubber for rubber raw rubber, first of all, by changing the vulcanizing agent and reinforcing filler, optimize the silicone rubber reinforcing structure control agent content formula, and then USES the Fe2O3, biomass graphene and carbon nanotubes to heat aging modification of silicone rubber, and USES the talcum powder, graphite powder and 26 type fluorine rubber to low permeability of modified silicone rubber. In the reinforcement study of silicone rubber sealing material, the influence of diisopropyl peroxide (DCP), silica black and structure control agent on mechanical properties and heat aging properties of silicone rubber were studied respectively. The results of DCP showed that with the addition of DCP from 0.4 PHR to 1.6 PHR, the tensile strength of samples aged at room temperature and 250℃×48h increased first and then decreased. The optimum addition of DCP is 1.0 PHR, and the tensile strength of the sample at room temperature and the tensile strength retention rate after aging can reach 7.66MPa and 64%. The results show that gas phase silica has the best reinforcing effect. The optimum filling amount of gas phase silica is 45phr, the tensile strength of the sample before aging and after aging at 250℃×48h can reach 7.66mpa and 4.87mpa, respectively, and the compression permanent deformation is 21%. The study of structural control agent shows that the composite of hydroxyl silicone oil/hexamethyldisilazane has better comprehensive properties. When the total amount of structural control agent is 9phr, the optimal ratio of hydroxyl silicone oil and hexamethyldisilazane is 1:1, the tensile strength of the vulcanized sample can reach 7.36MPa at room temperature, and the tensile strength retention rate of the sample after aging at 250℃×48h And elongation at break can reach 71% and 21% respectively. By comprehensive comparison, the best reinforcing formula of silicone rubber is: silicone rubber raw rubber 100phr, silica fume 45phr, hydroxyl silicone oil 4.5phr, hexamethyldisilazane 4.5phr,DCP1.0phr. The effects of Fe2O3, biomass graphene microsheets and carbon nanotubes on the properties of silicone rubber were studied. The results show that Fe2O3, biomass graphene microplates and carbon nanotubes can significantly enhance the thermal aging properties of silicone rubber. Compared with Fe2O3 and biomass graphene microsheets, carbon nanotubes have the best heat-resistant reinforcing effect. The optimal addition amount of carbon nanotubes is 0.9 PHR, and the tensile strength of the sample can reach 5.36MPa after aging at 300℃×12h, which is 105%, 9% and 17% higher than that of the blank sample, the sample with the optimal amount of Fe2O3 and the sample with the optimal amount of biomass graphene microflakes, respectively. In the study of low permeability modification of silicone rubber sealing material, talcum powder and graphite powder filling modification and fluorine/silicone rubber blending modification are used respectively. The filling modification study showed that both modified talc and modified graphite powder could significantly improve the air tightness of silicone rubber, and the comprehensive performance of the sample with modified graphite powder was better than that with modified talc powder. The optimal filling amount of the modified graphite powder is 15phr, and the gas permeability parameter of the sample is 5.16×10-15mol·m/ (m2·s·Pa), which is 26% lower than that of the blank sample. The study of fluorine/silicone rubber blends shows that the reduction effect of fluorine/silicone rubber blends on the permeability of vulcanized rubber is significantly better than that of modified talcum powder and modified graphite powder. When the total amount of fixed raw rubber is 100phr and the fluorine rubber blend ratio is 30%, the comprehensive performance of the blend is the best. The 200% fixed elongation stress of the sample is 38% higher than that of the sample without blending, and the oil resistance volume change and gas permeability parameters are 12% and 45% lower, respectively.

For the surface treatment of silicone rubber products, we usually use two methods of spraying matte oil or PU to improve and enhance the surface effect.   So which treatment process is better for spraying matte oil or spraying PU? Next, we will introduce the characteristics of these two processes separately.   Matte Oil is usually called Feeling Oil, which is the most commonly used process for surface treatment of silicone rubber products.   After the silicone rubber product is formed, the surface is usually astringent, the hand feeling is not very good, and it is easy to generate static electricity and absorb fine dust. Usually, we spray matte oil on the surface, which can reduce the generation of static electricity, improve the surface effect, make the hand feel more delicate and smooth, and increase the selling point of the product.   The matte oil has strong adhesion, the surface is smooth after spraying, the hand feels silky and the wear resistance of the surface is enhanced, and the alcohol resistance and salt spray performance are improved. This process is usually used in silicone rubber buttons, protective covers for electronic products, wristbands and other silicone rubber products.   PU is also called Polyurethane material. It belongs to an organic polymer material. Its characteristics are that it can effectively protect the characters and patterns on the surface of silicone rubber products. It has better wear resistance than matte oil and has a longer protection period. This remarkable feature is widely used in many fields, such as aviation, aerospace, automobile, light industry, electronics, construction, medical, chemical, energy and many other fields.   However, spraying PU also has its shortcomings. When we touch it with our hands, we feel that the surface is not as delicate as matte oil, slightly rough, and the rate of defective workmanship is relatively high, and the relative cost is also higher.
