Oil-resistant conveyor belt
Product Description
The covering layer of the oil proof conveyer belt uses the butadiene-acrylonitrile rubber with high content of acrylonitdta, using cotton canvas, nylon canvas or EP canvas as the strong layer, which is suitable for transferring oily matedals or some kind of oily condition(excluding fuel and solvent oil).
It has the advantage of Iow changing rate of volume, high intensity conservation rate, wide range of use.
