Platinum-Cured Silicone Gaskets

High Purity Silicone Gaskets

High purity platinum-cured silicone hygienic seals are the ideal choice for use in production facilities of fine pharmaceutical, biotechnology, high-purity water, injectables, food and beverage products.

TBL’s platinum-cured silicone gaskets withstand temperature extremes, radiation, corona, moisture and steam. Due to their smooth finish, platinum cured silicone gaskets resist product adhesion. These odorless, tasteless, non-toxic seals maintain product integrity and can be autoclaved, irradiated and gas sterilized. Since there is no benzoic acid residue, our platinum cured silicone hygienic seals provide you with the ultimate, high purity, contact surface.
