Silicones & Elastomers

Reiss Manufacturing’s Silicone Rubber division, also known as Ronsil, dates to the beginnings of the industry. Silicone elastomers were first developed during WWII as a high-temperature-resistant material. Dow Corning was established in 1943 to research and develop the potential of silicones, and General Electric opened its own plant shortly thereafter. Reiss Manufacturing began producing silicone rubber components in 1946.

Chemical engineering breakthroughs have enhanced silicone rubber’s resistance to extreme temperatures and aggressive chemicals, so that today it has broad applications, including within the automotive, electric, medical, and food industries.
