Vespel® sheet is a series of very durable polyimides that combine the greatest properties of plastics, metals, and ceramics. They are particularly resistant to wear and creep and operate at extremely high temperatures.
|SP-1||Mechanical and electrical parts at elevated temperatures. Valve seats, seals and insulators.||Unfilled. Provides maximum strength and elongation, the lowest modulus and thermal conductivity and optimum electrical properties.|
|SP-21||Lubricated or non-lubricated, low friction and wear applications. Valve seats, seals, bearings, washers, seal rings.||15% graphite filled. Provides enhanced inherent wear resistance and improves long term thermal stability.|
|SP-211||Low friction and wear applications in moderate temperature and PV environments. Bearings (bushings and washers).||10% PTFE, 15% Graphite filled. Provides the lowest static friction.|
|SP-3||Friction and wear applications in vacuum or inert gases. Bearings, piston rings and seals.||15% MoS2 filled. Provides the best wear performance in dry environments.|
Vespel® Rod and Vespel® Tube are also available.
