Vespel® is a high-performance polyimide material that is meticulously formed from resin by the well-respected company, DuPont. Polyimide materials, such as Vespel®, are characterized by a complex ring-shaped molecular structure that notably contains nitrogen atoms. This unique composition makes Vespel® one of the highest performing engineering plastics currently available on the market today. Remarkably, Vespel® does not melt; it can operate continuously under a wide range of temperatures, from low, cryogenic conditions all the way up to 550°F (288°C), with the ability to withstand occasional spikes reaching 900°F (482°C). Vespel® backup rings consistently exhibit superior performance across a variety of industrial applications that require low wear rates and extended operational life, particularly in extreme service conditions. At East Texas Seals Parker Distributor (ETS), we are dedicated to being your premier Vespel supplier, ensuring you have access to this exceptional material for your needs!
