Cast Urethane

Material Options

At Nuraseal, our polyurethanes offer high tensile strength, excellent abrasion resistance, unlimited shelf life, excellent hydrolytic stability, pressures up to 5000 psi and service temperatures up to 200°F. We utilize two main categories of elastomeric materials: liquid-cast thermoset ployurethane and injection-moulded thermoplastic polyurethane.


Thermoset Polyurethane

  • Exhibits excellent wear resistance, toughness, tensile strength and cut resistance.
  • Good fluid compatibility over a broad temperature range.
  • Highly resistant to ozone and radiation.
  • Available in hardness ranging from 60 ShoreA (rubber) to 85 ShoreD (hard plastic).
  • Shelf life is virtually unlimited.
  • Custom colours are easy to compound with minimal set-up or lead time.
  • Can be compounded with various additives including PTFE, UHMW polyethylene and molybdenum disulphide.
  • Parts can be manufactured for inexpensive tooling with minimal set-up costs.
  • Prototyping and lower volume production runs are fast and economical.

Thermoplastic Polyurethane

  • Exhibits good wear resistance, toughness, tensile strength and fluid compatibility.
  • Compounds available for applications ranging up to 130°C.
  • Available in hardness ranging from 80A to 70D.
  • Available in a variety of colours.
  • Production methods allow for large quantities to be manufactured economically.
