Acid and Alkali Resistance Belt

In order to fulfill the request of conveying materials under conditions of acid and alkali, we use cotton canvas, nylon canvas and EP canvas as the carcass during processes of designing and production, which creates properties of good elasticity ,trough-ability and low elongation. Through mixing materials with acid and alkali resistance as the cover, the product shows a good performance of chemical corrosion resistance and fine physical property.
