Equivalents & alternatives: UHMW-PE (PE-UHMW). Alt: HDPE (lower cost, less wear), acetal (stiffer/tighter tol), nylon (higher temp).
Tough, wear-resistant nylon — gears, rollers, wear pads, bushes. Cast grade for larger sections.
Engineering plasticLow-friction, dimensionally stable engineering plastic — precision parts, gears, bushes, manifolds.
Engineering plasticChemically inert, very low friction, wide temperature range — seals, slides, insulators, chem parts.
Engineering plasticTransparent and extremely impact-resistant — machine guards, glazing, light covers. Scratches unless hard-coated; attacked by solvents.
