Characteristics:- The rubber cover, which is made from chemical resistant materials, has fine anti-chemical corrosiveness and good physical property.
- It is specially made for those materials which would dissolve expand or corrode the belt.
- It is suitable for conveying material with chemical corrosiveness in chemical factory, chemical fertilizer factory, paper mill, mining industry etc.
