High Tear Strength Silicone for Demanding Industrial Applications
Our High Tear Strength Silicone Rubber is engineered to withstand the most demanding applications where durability and resistance to tearing are crucial. Without compromising its integrity, this material is perfect for industries where silicone components are exposed to intense stress, wear, and harsh conditions.
Key Highlights
- Exceptional tear and tensile strength
- Stable elasticity from –50°C to +220°C
- Resistant to heat, UV, ozone, and chemicals
- High durability under mechanical stress
- Custom hardness, color, and reinforced grades
