Saint-Gobain Performance Plastics manufacturers a line of fiberglass-reinforced silicone solid rubber.

The fiberglass increases the products dimensional stability for high-pressure applications, while functioning over a wide temperature range. Most products feature different solid silicone rubber durometers (hardness) on both sides of the fibreglass reinforcement. We also offer a product with a closed cell silicone sponge on both sides of the fiberglass substrate. Materials can be supplied in yard goods and sheets, with and without pressure-sensitive adhesive on one side. Thicknesses range from .032 (.81mm) up to .125 (3.17mm).

Products are designed for various ranges of pressure and temperature resistance. COHRlasticpads are often chosen for their long service life in demanding circuit board laminating operations.
