Crompton Corp.´s Urethane Technology Group has introduced a family of polyurethane prepolymers available in six grades it claims provide substantial improvement in abrasion resistance. Called Adiprene Extreme, the family of wear-resistant cast elastomers consists of three ether and three ester grades, a spokeswoman said. A patent is pending on the new prepolymers. "Adiprene Extreme castable elastomers represent the cutting edge in urethane prepolymer technology today," according to Naureen Stone, global manager for the Urethane Technology Group. "Their excellent physical and dynamic properties, coupled with outstanding abrasion resistance, make them the perfect choice for demanding applications that require a non-conventional urethane." Crompton developed Adiprene Extreme as a niche product primarily to fill that need, she said. The prepolymers offer improved abrasion resistance in dry, aggressive, sliding applications such as elastomeric pads for tracked vehicles, scraper blades and mining screens, the company said. Other potential applications include in-line skate brakes along with drive tires and rolls. For more information, call 203-573-2000 or visit www.cromptoncorp.com.
