High-strength type. Adopt vinyl silicone rubber or low phenyl silicone rubber, use gas phase white carbon black with large specific surface area or modified white carbon black as reinforcing agent, and add comprehensive processing aids and special additives. Cooperate with the improvement measures to improve the cross-linked structure and increase the tear strength.
High temperature resistant type. By using vinyl silicone rubber or low phenyl silicone rubber, the type of reinforcing agent and heat-resistant additive can be appropriately selected, and a silicone rubber resistant to a high temperature of 300-350 ° C can be obtained.
Low temperature type. Low phenyl silicone rubber, brittle temperature of -120 ℃, still elastic at -90 ℃.
