Acid and alkali-resistant Belt
 
In order to meet the clients’ requirement to convey materials with chemical corrosiveness, when design and manufacture, we use nylon, cotton or EP fabric as core, which makes the belt with good elasticity, troughability and low elongation. And adopt chemical resistant materials mixed with rubber as cover, which makes the belt with good performance in acid and alkali-resistance.
 
Application
  • Chemical factory, chemical fertilizer factory, paper mill, mining industry, etc.
