Description

Vespel® rod is a high-performance material. It has high strength but very little resistance to acids, alkalis, and steam. It has excellent wear, impact, and creep resistance.

Key Features

  •   Temperature: continuous up to +288°C (+482°C short term).
  •   Outstanding strength and impact resistance.

Applications

Vespel® Grade Application Composition
SP-1 Mechanical and electrical components at high temperatures Seals, valve seats, and insulators Unfilled. It has the highest strength and elongation, the lowest modulus and thermal conductivity, and the best electrical properties.
SP-21 Applications with low friction and wear, whether lubricated or unlubricated. Seals, valve seats, bearings, washers, and seal rings 15% of the space is filled with graphite. Improves long-term thermal stability and provides increased inherent wear resistance.
SP-211 Applications with low friction and wear in moderate temperature and PV environments. Ball Bearings (bushings and washers). 10% PTFE, 15% graphite. Provides the least amount of static friction.
SP-3 Applications for friction and wear in vacuum or inert gases. Bearings, piston rings, and seals are all examples of mechanical components. MoS2 is 15 percent filled. In dry environments, it has the best wear performance.
