TPU

Thermoplastic Polyurethane
Gaskets · Grips · Dampers

A firm, rubber-like elastomer for parts that bend, compress, grip, or seal — Shore 95A, so it flexes without going soft.

Strengths
& uses

When the part needs to behave like rubber — sealing, gripping, absorbing, or flexing under load. Softer durometers are available on request.

Strengths
  • Shore 95A — firm and rubber-like
  • Abrasion and tear resistant
  • Resists oils and grease — acids and alkalis are its weak spot
  • Compresses and springs back
Common applications
  • Gaskets and seals
  • Soft-touch grips
  • Vibration dampers
  • Protective bumpers
