Vespel® sheet is a collection of highly durable polyimides combining the best characteristics typically found in plastics, metals and ceramics. They are highly resistant to wear, creep and have extremely high operating temperatures.
Temperature: Up to +288°C continuous (+482°C short term).
Key Features: Outstanding wear resistance and easily machinable. Low thermal and electrical conductivity. Withstands loads at high temperatures.
||Mechanical and electrical parts at elevated temperatures. Valve seats, seals, insulators.
||Unfilled. Provides maximum strength and elongation, the lowest modulus and thermal conuctivity and optimum electrical properties.
||Lubricated or non-lubricated, low friction and wear applications. Valve seats, seals, bearings, washers, seal rings.
||15% graphite filled. Provides enhanced inherant wear resistance and improves long term thermal stability.
||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.
||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.
Also available: Vespel® Rod
|Sheet Size (mm):
||254 x 254, 127 x 127
||1.6 to 50.8
