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

Delrin      Delrin is an engineered plastic with a good combination of toughness, stiffness, wear and abrasion resistance, and low frictional characteristics. 

Nylon      Nylon, comprising several grades of polyamides, is a general-purpose material in wide use. It is tough and resistant and has good pressure ratings.    

Polycarbonate      Polycarbonate is an extremely tough polymer that can be machined to close tolerances.  Lubrication is sometimes needed, as the wear properties of polycarbonate are not as good as some other polymers.   

Other Plastic      Other unlisted or specialized polymers or plastic materials.
