Characteristics:
The core of Acid Alkali Resistant Conveyor Belt is made of cotton canvas, nylon canvas or polyester canvas. It has good elastic belt body and good grooving performance and low elongation rate. The cover rubber is made of acid and alkali resistant material, with erosion resistance and physical characteristics.
Usage:
It is suitable for conveying acid and alkali materials. It is widely used for corrosiveness materials in chemical factories, chemical fertilizer factories, paper mills and industry.
