Oil Resistant Conveyor Belts, Rubber Conveyor Belts, NBR Conveyor Belt China
- 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.

After-aging properties of rubber cover(70℃×168h):
Change rate of tensile strength and breaking elongation are both not more than 25% of before-aging values.
