Plastic chains have been developed for light duty power transmission applications. They can be used with steel or plastic-type material sprockets, and perform a variety of speeds.
A real advantage of plastic roller chain is that it could perform in harsh chemicals, moisture and different temperature applications.
They self-lubricate and so are perfect for Leaf Chain applications where cleanliness is important. Meals processing, medical and 
pc equipment and clean rooms are normal uses for plastic-type roller chain.
