Usage
Acid-alkaline resistant steel cord conveyor belt is suitable for conveying materials with chemical corrosiveness in
chemical factories, chemical fertilizer factories, paper mills,
mining industries, etc.
Characteristics
Steel cord conveyor belt selecting steel cord as the carcass, the belt has good elasticity
and excellent troughability. The rubber cover, which is made from
acid- alkaline resistant materials, has great anti-chemical
corrosiveness and good physical properties.
