描述

SPEC SHEET: Polyurethane (PU, AU, EU) 90 Durometer.pdf

Polyurethane (PU, AU, EU)

Material Description

The millable Polyurethane (PU) rubbers are distinguished into two types; the first is polyester urethane (AU) and the other is polyether urethane (EU). AU
type urethanes have outstanding oil, fuel and solvent resistance but can be attacked by hydrolysis. EU type urethanes are not attacked by hydrolysis and
still offer a fuel and oil resistance comparable to low ACN (18 to 22% ACN) Nitriles or HNBRs. Any type polyurethane has excellent wear resistance, high
tensile strength and high elasticity in comparison with any other elastomers. We can also offer any type thermoplastic urethane (TPU).

Cure system: Peroxide-cured

Standard PU compounds are peroxide-cured.

Temperature Range:

Standard Low Temp: -40°C (-40°F)

Standard High Temp: 80°C (176°F)
