The characteristics of rubber parts determine their use. Generally, everyone knows that rubber products are made of methyl vinyl silicone rubber as the base rubber, and various fillers (heat-resistant agent, reinforcing agent, modified Agents, etc.) are made by filtration, molding, mixing, extrusion, thinning, vulcanization, bonding and other production processes. Vulcanized rubber products have the following characteristics:
1. Electrical insulation properties: The dielectric properties of silicone rubber are excellent, especially the dielectric properties at high temperatures are much higher than those of ordinary organic rubbers, and the dielectric strength is almost unaffected by temperature in the range of 20-200 °C.
2. Excellent high temperature compression set.
3. With the advantages of good processing performance and easy molding, various products can be produced by extrusion hot air vulcanization molding, die addition molding, and extension molding.
4. High and low temperature resistance: It can be used for a long time at 200 °C, and still elastic at -60 °C.
5. Excellent weather resistance, ozone resistance and ultraviolet radiation resistance, and no cracking occurs when used outdoors for a long time. It is generally believed that silicone rubber can be used outdoors for more than 20 years.
