High-strength white carbon black, surface-treated white carbon black and some special compounding agents in silicone rubber; use silicone rubber together with other organic polymers to improve tear resistance; change silicone rubber molecular link Structure, synthesis of new silicone rubber with high tear resistance.

The main components of silicone rubber compound are: raw rubber, reinforcing filler - commonly used as white carbon black, structural control agent to prevent interaction between white carbon black and raw rubber, heat-resistant additives - commonly used trioxane Iron is used as a peroxide for the crosslinking agent. Tests have shown that the use of highly dispersible meteorological method silica is beneficial to improve the strength and tear resistance of vulcanizates.

High tear-resistant silicone rubber materials can be used to make a variety of products such as: seals, gaskets, films, industrial and medical silicone rubber tubes.
