Plastic Roller Chain

Fully manufactured plastic roller chain is a standard in-stock item. It is available in ANSI #25, #35, and #40 sizes. We have these chains on the shelf in acetal, derlin, kynar, nylatron, and polypropylene material options. Plastic roller chains are in stock as 10ft boxes but can be supplied in other lengths upon request. We can also manufacture other sizes of plastic roller chain upon request. It is important to note that because of the construction of the plastic roller chain, additional connecting links are not needed. The pin links have the capability of being dis-assembled and re-assembled.

Plastic Roller Chain Sprockets

We also stock a full line of plastic sprockets. #25 and #35 plastic sprockets are manufactured out of high quality dark grey/black nylatron, and #40 plastic sprockets are manufactured out of white UHMW or green nylon. The below chart is the standard #25 - #40 chain size plastic roller chain sprockets that are in-stock.

Plastic Roller Chain Materials

The Acetal plastic that is used is white in color and is a custom engineered POM plastic that is made to use with high precision parts that require a high stiffness. This plastic features low friction and excellent dimensional stability. This is a good option for applications that require a plastic roller chain that is self lubricating, high-precision, and can operate in a wide range of temperatures (-4°F to +180°F).

The Delrin plastic that is used is white in color and is a homopolymer acetal. This material has low moisture absorption, high strength, and is FDA compliant. If your application is requiring a high-strength FDA compliant plastic roller chain that is also resistant to corrosion, then this is the one to use.

The Kynar plastic that is used is a natural resin material that offers excellent resistance to corrosion and chemicals in both ambient and elevated temperatures. Kynar is U.V. stable, mechanically tough, and flame resistant. Kynar plastic roller chain is typically used in chemical processing, fluid handling, water systems, and fire safe componentry applications. This plastic also meets FDA requirements and is easy to machine if edits need to be made.

The Nylatron GS plastic that is used is dark grey to black in color and is a molybdenum disulphide filled nylon plastic that offers high strength and rigidity. This is a good option for plastic roller chain due to the strength, good mechanical and electric properties, and self-lubrication of the chain.

The Polypropylene (PP) plastic that is used is grey in color and is a thermoplastic polymer that is resistant to cracking, abrasion, and has a high melting point. Polypropylene plastic roller chain is best used in packaging, laboratory equipment, automotive, and any application that requires a low-friction, anti-corrosive, and high-strength plastic chain.

Poly-Steel Plastic Roller Chain

Lastly in the plastic roller chain lineup is poly steel chain. This chain is used in applications needing most of the same properties that a solid polypropylene chain has but with higher strength. The inside links are manufactured out of polypropylene and the outside links and pins are manufactured from 304-grade stainless steel. The natural white PP with stainless steel (the photo on the top left) is used in standard applications, while the blue PP with stainless steel (the photo on the top right) is used in applications that require a food-grade roller chain.
