Polyurethane O-Rings - Cast Urethane O-Rings

Polyurethane rubber is a thermoplastic elastomer formed by reacting a polyol with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Polyurethane rubber is widely used due to its high strength, and excellent tear and abrasion resistance. Polyurethane also provides excellent permeation resistance.

Polyurethane O-rings

Polyurethane O-rings are made of millable Polyurethane rubbers distinguished by two types; one is polyester urethane (AU), the other is polyether urethane (EU). AU type polyurethane o-rings have outstanding oil, fuel and solvent resistance but can be attacked by hydrolysis. 

EU type polyurethane O-rings are not attacked by hydrolysis and still offer a fuel and oil resistance comparable to low ACN ( 18~22% ACN) nitriles or HNBRs. Any type polyurethane O-rings has excellent wear resistance, high tensile strength and high elasticity in comparison with any other elastomers.

We also can offer any type thermoplastic urethane (TPU).

Service Temperature: The Service Temperature of PU is -40° C to 80° C, shortened lifetime up to 100 C.

Hardness: 60 to 93 Deg Shore A are available.

Color: Black, transparent, green, orange are available, or any assigned Color from customers.

Application: Polyurethane O-rings are usually are applied in mechanical industries, especially in places that require higher wear resistance and higher strength.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.
