Poly-Texx Z combines the strength of Nylon with the resilience and wear resistances of Kevlar aramid fibers. This unique combination results in a material that is strong and extremely stiff. The aramid fibers along with Nylon’s inherent strength combine to create a material that has exceptional wear properties. The fibers give Poly-Texx Z exceptional abrasion resistances making it an ideal choice for rollers, chain guides, and rollers. Because the base polymer Nylon is hygroscopic, care should be taken to account for moisture when designing Poly-Texx Z into an application. Available in sheet, rod, and tubing, it is easily machined with standard metal working equipment. Tolerances of +/-.001 can be achieved with experience.
