Plastic Machining Company offers roller chains in nylon, acetal, Delrin®, and polypropylene.
Most plastic roller chains can be used with steel or plastic sprockets, work under a wide range of speeds and loads. Plastic chain and drive components excel in harsh chemical, high-moisture, and high-heat environments.
Oil-filled nylon features self-lubrication, ideal for food processing machinery. Nylon has a low coefficient of friction as well as desirable abrasion and chemical resistance. Nylon is a rigid material, which resists creep and distortion of sprocket key-ways under high loads. Sprockets made from oil-filled nylon include those used with roller chain and flat top chain.
Although somewhat brittle, acetal (also known as Delrin®), offers incredibly close tolerances and resists creep. It has a low coefficient of friction and a fair but lower abrasion resistance versus other roller chain plastics.
Polypropylene is designed for lower load applications but offers a balance of thermal, chemical, and electrical specs. Polypropylene features a low coefficient of friction and fair impact and abrasion resistance for its cost effective price.
