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

Plastic Screw Gears Delrin Delrin can be an engineered plastic with a good 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 has good pressure ratings.

Polycarbonate Polycarbonate is an extremely challenging polymer which can be machined to close tolerances. Lubrication may also be needed, as the use properties of polycarbonate aren’t as good as various other polymers.

Other Plastic Additional unlisted or specific polymers or plastic materials.
