Silicone Rubber Feature:
1. High temperature performance.
2. Excellent low temperature performance. Silicone rubber glass transition temperature is generally -70 ~ -50 ℃, special formula up to -100 ℃
3. Excellent weatherability.
4. Electrical performance.
5. Physical and mechanical properties.
7. Gas permeability.
8. Physiological inertia. Silicone rubber non-toxic, tasteless, odorless, non-adhesion with human tissues, with anti-clotting effect on the body tissue reactivity is very small. Particularly suitable as a medical materia
