Norseal® Silicone Rubber Solutions The Norseal Silicone Advantage Saint-Gobain® Norseal Silicone Rubber is a family of high-performance products featuring a unique chemical structure that provides high temperature stability and general inertness unavailable in any other elastomer. As a result, Norseal Silicone Rubber works in applications where no other material can be used. These high performing products are frequently used in a variety of applications and many markets including military, aerospace, electronics, life science, transportation, LED lighting, electric vehicles (EV) and...

Thermal Stability Time/Temperature Resistance Silicone’s physical properties are not adversely affected by Based on temperature for 8 hours daily until rubber can no longer be elongated 50% prolonged exposure to temperatures from -100°F to +500°F. In addition, it can withstand intermittent exposure to even higher temperatures (Time/Temperature Resistance). Silicone far outdistances other elastomers in resistance to thermal degradation and outperforms in general service life, compression set resistance, electrical strength and non-stick properties. Silicone also delivers good chemical and...

Reinforced Solid Rubber Norseal Silicone Reinforced Solid Rubber with fiberglass increases the product’s 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 fiberglass reinforcement. We also offer a product with a closed cell silicone sponge on both sides of the fiberglass substrate. Materials are available in yard goods and sheets, with and without pressure-sensitive adhesive on one side. Thicknesses range from .031" (.79mm) up to .125"...
