Spring energized PTFE seal , originally developed the spring-energized PTFE seal to meet cryogenic requirements in the aerospace industry. Since that initial success, the company has continued to develop both materials and canted coil spring technology to meet today's demanding sealing requirements.
Our advanced seal material formulations, which blend high performance fibers and polymers with PTFE, enable our solutions to constantly push today's known sealing application envelopes
They are typically used in areas where elastomeric seals cannot meet the frictional, temperature, or chemical resistance requirements of the application. Seals made of PTFE have exceptional resistance to high temperature, chemical reaction, and corrosion, and provide the lowest coefficient of friction of all sealing materials. Compared to other elastomeric sealing materials (e.g. Polyurethane, Nitrile and Viton® Rubber), Teflon® is a plastic material and offers little or no memory after being compressed; therefore, seals made out of Teflon® need to incorporate an energizing element made of an elastomer material, usually rubber (rubber-energized) or a metal spring (spring-energized).
