Material Acetal Acetal is a stable plastic-type material with inherent self-lubricating properties which can be improved with lubricating fillers.

Delrin Delrin can be an engineered plastic-type material with a good mixture of toughness, stiffness, use and abrasion resistance, and low frictional features.

Nylon Nylon, comprising several grades of polyamides, is a general-purpose material in wide use. It is hard and resistant and offers great pressure ratings.

Polycarbonate Polycarbonate can be an extremely challenging polymer which can be machined to close tolerances. Lubrication may also be needed, as the wear properties of polycarbonate are not as good as some other polymers.

Other Plastic Various other unlisted or specific polymers or plastic materials.
