Material Acetal Acetal is certainly a stable plastic material with inherent self-lubricating properties which can be improved with lubricating fillers.
Delrin Delrin can be an engineered plastic with a good Plastic Screw Gears mixture of toughness, stiffness, use and abrasion level of resistance, and low frictional characteristics.
Nylon Nylon, comprising several grades of polyamides, is a general-purpose material in wide make use of. It is difficult and resistant and has good pressure ratings.
Polycarbonate Polycarbonate is an extremely hard polymer which can be machined to close tolerances. Lubrication is sometimes needed, as the wear properties of polycarbonate are not as good as various other polymers.
Other Plastic Various other unlisted or specialized polymers or plastic materials.
