Silicone Sponge - National Silicone™ Silicone Rubber

Solid Silicone Sheeting

Commercial, FDA, ZZR, Electrically Conductive, Fiberglass Reinforced Grades

Our series of solid silicone sheet are constructed using a high silicone polymer mixture which translates to exceptional performance across all durometers. Designed with a long service life in mind, these materials provide excellent resistance to chemicals, fluids, and extreme temperature environments. Manufactured in continuous rolls, in standard and specialty grades, with a smooth surface finish on both sides. These products are currently available for sale in North America, Europe & Asia.

 

Closed Cell Silicone Sponge

Soft, Medium, Firm, Extra Firm, Flame Retardant Grades

Our closed cell silicone sponges are excellent for conditions that require a soft compressible material with high-performance properties. Providing extra strength and durability, these materials are versatile and are ideal for extreme temperature environments in gaskets and sealing applications. Manufactured in continuous rolls, in four firmness grades, with a fabric impression surface finish on both sides. These products are currently available for sale in North America, Europe and Asia.

Cellular Silicone Foam

Ultra Soft, Extra Soft, Soft, Medium, Firm, Extra Firm, Automotive Grades

Our series of cellular silicone foams are engineered for longevity and high performance. They excel in conditions that require low compression set, high temperature stability, low temperature flexibility and need to be UL 94 flame rated. Manufactured in continuous rolls in various grades, with both a smooth and fabric impression surface finish (depending on the grade). These products are currently available for sale in North America, Europe and Asia.

 

Silicone BASE

HTV/HCR & LSR
