Oil Resistant Conveyor Belts, Rubber Conveyor Belts, NBR Conveyor Belt China
1. Applications
Oil resistant conveyor belt is suitable for transporting oily materials, or used in environment exposed to working oil. We select NBR as belt covers. NBR has a high content of acrylonitrile with excellent oil resistant property.
