1, high-speed rotary seals can use silicone. Silicone by silicon, oxygen atoms to form the main chain, the side chain for the carbon-containing groups, the dosage is greater is the side chain for the vinyl silicone rubber. Both heat-resistant and cold-resistant, the use of temperature between 100-300 ℃, it has excellent weather resistance and ozone resistance to use good insulation.
2, the disadvantage is the low strength, tear resistance is poor, wear resistance is also poor. Silicone rubber is mainly used in the aviation industry, electrical industry, food industry and medical industry.
