Equivalents & alternatives: PA6 cast (Nylatron for filled). Alt: PA66 (stiffer/higher temp), acetal (better dimensional stability), UHMWPE (better wear/impact).
Low-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 plasticUltra-high wear + impact resistance, self-lubricating — wear strips, guides, chute liners, star wheels.
Engineering plasticTransparent and extremely impact-resistant — machine guards, glazing, light covers. Scratches unless hard-coated; attacked by solvents.
