Material Acetal Acetal is certainly a stable plastic material with inherent self-lubricating properties that can be enhanced with lubricating fillers.
Delrin Delrin can be an engineered plastic-type with a good combination of toughness, Plastic Screw Gears stiffness, use and abrasion resistance, and low frictional characteristics.
Nylon Nylon, comprising many grades of polyamides, is a general-purpose materials in wide use. It is challenging and resistant and offers good pressure ratings.
Polycarbonate Polycarbonate can be an extremely challenging polymer which can be machined to close tolerances. Lubrication may also be needed, as the put on properties of polycarbonate are not as good as various other polymers.
Other Plastic Other unlisted or specialized polymers or plastic components.
