Vespel® Sheet

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.

Key Features

  •       Temperature: constant up to +288°C (+482°C short term).
  •       Excellent wear resistance and machinability.
  •       Low thermal and electrical conductivity.
  •       Withstands high-temperature loads.

Applications

Vespel® Grade Application Composition
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.

Availability

Vespel® Rod and Vespel® Tube are also available.
