<p>Heat curable fluorosilicone rubber compositions curable to products having reduced shrinkage at elevated temperatures, increased solvent resistance and increased resiliency as well as excellent elongation, tear resistance, and hardness properties, are provided herein by reacting a binary filler system composed of a reinforcing silica filler and a potassium aluminosilicate filler with an alkenyl- and silanol-terminated diorganopolysiloxanes base polymer gum and an alkenyl- and silanol-terminated diorganopolysiloxanes crosslinking gum and then combining the resulting composition with an organic peroxide catalyst.</p> |
