High Hardness Silicone Rubber Solutions
What Is High Hardness Silicone Rubber?
High hardness silicone rubber is a silicone elastomer designed with higher Shore A hardness compared with standard soft silicone rubber. Common hardness grades include 70 Shore A, 80 Shore A, and 90 Shore A, making it suitable for applications that require better dimensional stability, deformation resistance, mechanical strength, and heat resistance.
It is also commonly searched as high durometer silicone rubber, hard silicone rubber, high hardness HTV silicone rubber, or high hardness HCR silicone rubber. Depending on the application, the material can be processed by compression molding, extrusion, calendering, die cutting, or custom fabrication.
