POLYURETHANE (AU) (EU)
Millable polyurethane exhibits excellent abrasion resistance and tensile strength as compared to other elastomers providing superior performance in hydraulic applications with high pressures, abrasive contamination and shock loads. Fluid compatibility is similar to that of nitrile at temperatures up to approximately 175 °F. At higher temperatures, polyurethane has a tendency to soften and lose both strength and fluid resistance advantages over other elastomers.
Application Advantages
excellent strength and abrasion resistance
good resistance to petroleum oils
good weather resistance
Application Disadvantages
poor resistance to water
poor high temperature capabilities
Primary Uses
O-rings, rubber seals and custom molded rubber components for:
seals for high hydraulic pressure
highly stressed parts subject to wear
