Acid alkali resistant conveyor belts
Product specifications:Customized according to the manufacturer
Product Details


Features and application:The cover adopts combination of rubber and plastic filled with excellent acid-resistant and alkali-resistant inert material which takes more advantages compared with neoprene acid and alkali-resistant belt. Frame material adopts EP canvas which makes the performance be more reliable than belt with cotton canvas core.lt is suitable for conveying material with chemical corrosiveness in chemical factory, chemical fertilizer factory, paper mill, mining industry etc.

The standards:HG/T3782-2015(<acid alkali resistant conveyor belts》
