Plastic Roller Chain
MATERIAL DATA
In order to meet the range of strength, chemical and heat resistance requirements of the marketplace, Plastock offers chains and sprockets molded from four standard materials: Polypropylene, Delrin (Acetal), Kynar PVDF and Nylatron GS molybdenum disulfide filled nylon. Performance data on the base polymer products described below should be used in the selection of the specific material for the application involved.
