Silicone rubber materials are based on silicon-oxygen bonds as the main chain, and their excellent heat resistance, cold resistance, dielectric properties and other properties are widely used in life, industry and other fields. Due to the scope of use and the upgrading of demand, the use temperature of more silicone products also needs to be increased accordingly, through the research and development of technology, high-temperature silicone rubber appeared in front of the public, today Guangzhou Zhongxiang and everyone the characteristics and uses of high-temperature silicone rubber materials.
What is the high temperature resistant silicone rubber material:
High-temperature silicone rubber materials have outstanding high-temperature resistance, as well as excellent weather, oil, corrosion, abrasion and low-temperature resistance. The high and low temperature resistance of ordinary silicone rubber is about -55 to 220, and the high temperature resistance silicone rubber can reach -75 to 300 after the introduction of phenyl group, and sometimes even low temperature can reach -110, and the maximum temperature can reach about 350 degrees Celsius in a short period of time. Guangzhou Zhongxiang**'s WACKER Silicone Rubber Wacker R750 series and Bluestar HCR 70THT are high-temperature silicone rubbers with particularly good high temperature resistance.
Features of high temperature resistant silicone rubber material:
1) Excellent heat resistance, cold resistance, and dielectric properties.
2) The main characteristics of high-temperature resistant silica gel are high and low temperature impact resistance, rapid dredging, extremely low odor, and the release during dredging is harmless to the human body.
3) Excellent heat resistance, ozone resistance, chemical attack resistance, excellent electrical insulation performance, excellent thermal conductivity, thermal conductivity up to 08-1 provides a high guaranteed thermal conductivity for electronic products, ensures the stability of the product, and improves the performance and life of the product.
4) The component system is simple and convenient to use, and there is no need to use primer for bonding with a variety of substrates. Excellent elastomer, colloidal elasticity and toughness, no bubbles, excellent adhesion and adhesion to various metal materials, not easy to peel off, so we can apply a wide range of high-temperature resistant silica gel according to the characteristics.
Application fields of high-temperature resistant silicone rubber materials:
Because silicone rubber has the characteristics of high temperature resistance, oxidation resistance, corrosion resistance, and good electrical insulation, it is widely used in electronic power, medical, food, aerospace and other fields.
1) Widely used in boiler seals and household appliances: this kind of high-temperature resistant silica gel material can withstand high temperature up to 315, and the temperature resistance time can reach 1000 hours, and is generally used for high-temperature seals.
2) High-temperature resistant silicone materials are used in industry: high-temperature vulcanized pipes, high-temperature exhaust hoses, double-layer exhaust hoses, temperature-resistant telescopic hoses, etc.
3) High-temperature resistant silica gel is widely used in bonding, insulation, thermal conductivity, moisture-proof, shockproof and sealing of electronic components under high-temperature working conditionsElectronic and electrical industry, engineering industry, aircraft manufacturing, automobile model, aerospace mold making, etc., electric heating pipe application, microwave oven silicone strip, electric iron high-temperature furnace, oven and other products of adhesive sealing requirements high temperature and so on.
4) High temperature resistant silicone material is also used in medical food and other fields.
The above is the characteristics and application fields of high-temperature resistant silicone rubber materials, if you have any questions about silicone rubber materials, please consult.
