High-Temperature Silicone Rubber Sheets, Bars, and Strips

Also known as polysiloxane, this silicone rubber offers good resistance to ozone and salt water. Softer durometer rubber has better conformability; harder durometer rubber is more wear resistant.

High-Strength High-Temperature Silicone Rubber Sheets and Strips

Greater strength than standard High-Temperature Silicone translates into better shock-absorbing qualities and longer life. Silicone, commonly called polysiloxane, offers good resistance to ozone and salt water.
