About Silicone
Silicone rubber is an inorganic synthetic elastomer made from a cross linked silicone-based polymer reinforced with filler. It offers a unique combination of chemical and mechanical properties as compared to organic elastomers. Silicone is used across a wide array of applications and industries. Its inherent purity, inertness and biocompatibility make silicone the preferred choice of elastomer in the biomedical, pharmaceutical and healthcare industries.
