Polyurethane (PU, AU)

Selection Guide

Polyurethane is an organic polymer formed by reacting a polyol alcohol with a cyanate in the presence of suitable catalysts and additives. The result of this reaction is a thermoplastic elastomer, and therefore demonstrates drastically different mechanical properties than elastomeric rubbers. For example, Polyurethane O-rings, gaskets, & custom molded parts generally have two or three times greater tensile strength and wear resistance than Nitrile and comparable polymers. Polyurethane O-rings, gaskets, & custom molded parts also provide excellent permeation resistance when compared to most rubbers. However, the plastic material becomes brittle at low temperatures and will begin to warp and flow at high temperatures, making polyurethane O-rings, gaskets, & custom molded parts not suitable for some applications. Polyurethane O-rings, gaskets, & custom molded parts are most commonly used in hydraulic systems and other applications where high pressure and wear resistance are critical, but extreme temperatures are not a factor.
