Adding a thermoplastic material with a certain melting temperature or softening temperature to the vinyl silicone rubber, the thermal shrinkage of the silicone rubber compound can reach 35% to 50%. No two-stage curing type is required. It is made of vinyl silicone rubber with high vinyl content, which is controlled by controlling the pH value of raw rubber and compounding agent, and adding special additives.
