Urethane O-Ring (Polyurethane &#; PU, AU, EU) Material Description

If you want to learn more, please visit our website Sanshi.

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. Global O-Ring and Seal offers urethane o-rings in 70 and 90 durometer. We can also offer any type thermoplastic urethane (TPU).

Urethane o-rings are typically transparent (clear) in color, and have an unlimited shelf life.

Cure System: Peroxide-Cured

Standard polyurethane compounds are peroxide-cured.

Polyurethane O-Ring

Polyurethane O-Rings are especially suited wherever O-Rings are subject to dynamic loads. This includes, for example, applications in hydraulics, pneumatics and in a wide range of other critical areas. In many cases, polyurethane O-Rings are used instead of NBR due to their high mechanical strengths.
