Aerospace Valve Seats & Seals
Curbell Plastics, Inc., one of the nation’s premier suppliers of plastic sheet, rod, tube and film today released a new technical white paper exploring the use of DuPont™ Vespel® parts and shapes in aerospace valve applications.

Titled DuPont™ Vespel® Polyimides - High Performance Polymers for Aerospace Valve Seats and Seals, the paper describes how sealing components made from DuPont Vespel can enhance the reliability and extend the operating temperature range of aircraft and spacecraft valves.

Topics in this paper include designing seals for high temperature and low temperature environments, holding tight dimensional tolerances and achieving superior friction and wear performance without the use of liquid lubricants.

“Aerospace valves must operate reliably in extreme conditions including high temperatures, cryogenic temperatures, and in some cases, vacuum environments,” stated Keith Hechtel, Curbell Plastics Senior Director of Business Development and co-author of the paper. “DuPont Vespel parts and shapes have unique performance characteristics that result in reliable seals in even the most demanding conditions. We think this will be a great technical resource for designers of aerospace valves.”
