Some of
our best work
goes unseen

Materials technology: AU [polyurethane]

Polyurethane offers the highest abrasion resistance of all elastomers, combined with:

  • excellent oil, fuel and solvent resistance
  • excellent low temperature properties
  • high ozone and oxygen resistance
  • high tensile/tear strength.

At DP Seals we pride ourselves on being able to provide specialist advice in selecting and developing exactly the right blend of materials to meet a vast range of performance requirements. If you are unsure about what material might be best, call us on +44 (1202) 674671 or email our .
