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

Delrin Delrin can be an engineered plastic with a good Plastic Screw Gears combination of toughness, stiffness, wear and abrasion level of resistance, and low frictional characteristics.

Nylon Nylon, comprising many grades of polyamides, is a general-purpose material in wide make use of. It is challenging and resistant and provides great pressure ratings.

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

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