Silicone Rubber Solutions

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 packaging....

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 fluid...
