Silicone rubber is a high-performance rubber material that is polymerized from compounds such as silane (SiH4) and siloxane (SiO2). Silicone rubber has the following properties and uses:
1. Properties of silicone rubber:
1. High temperature resistance: Silicone rubber can be used at extremely low or extremely high temperatures. The long-term use temperature range can reach -60°C ~ 200°C, and the short-term use temperature can reach -100°C ~ 350°C;
2. Weather resistance: Silicone rubber can still maintain good physical properties and appearance under the influence of long-term ultraviolet rays, oxygen, moisture, corrosion and other natural environments;
3. Chemical resistance: Silicone rubber has good oil resistance, solvent resistance, acid and alkali resistance, oxidation resistance and other properties;
4. Electrical insulation: Silicone rubber has good electrical insulation properties;

5. Biocompatibility: Silicone rubber does not contain carcinogens and has good compatibility with biological tissues.

2. Application of silicone rubber:
1. Medical devices: Silicone rubber can be used to manufacture medical devices and prostheses, such as artificial heart valves, cochlear implants, etc.;
2. Electronic appliances: Silicone rubber can be used to manufacture high-temperature wires and cables, electronic components, batteries, etc.;
3. Automobile industry: Silicone rubber can be used in automobile manufacturing, such as engine seals, automobile glass seals, automobile tires, etc.;
4. Construction industry: Silicone rubber can be used for building door and window seals, roof waterproof seals, ground waterproof seals, etc.;
5. Food industry: Silicone rubber can be used for seals and conveyor belts of food processing machinery.
In short, silicone rubber has a variety of excellent properties and a wide range of uses, and is a high-performance rubber material.
