(1) Introducing special groups (such as phenyl) into the side chain of silicone rubber molecule to prevent the oxidative degradation of side groups and the thermal rearrangement degradation of main chain;

(2) Larger segments (such as phenylene, CYCLODISILAZANE and carbodecaboralkyl) were introduced into the main chain of silicone rubber to improve the thermal stability of crosslinking bond of vulcanizate;

(3) Heat resistant additives (such as SnO2, Fe2O3, etc.) are introduced into the compound formulation system to prevent the cyclization degradation of the main chain and the oxidative crosslinking of the side chain. Among them, the most commonly used and effective method is to introduce heat-resistant additives into the compound formula system.
