Suitable for working environments that come into contact with acid and alkali, such as phosphate fertilizer manufacturing, seawater exposure to salt, and covering with rubber and plastic blends filled with inert materials with excellent acid and alkali resistance, which have better performance than chloroprene rubber acid and alkali resistant conveyor belts. Suitable for working environments that come into contact with acid and alkali, such as phosphate fertilizer manufacturing, seawater exposure to salt, and covering with rubber and plastic blends filled with inert materials with excellent acid and alkali resistance, which have better performance than chloroprene rubber acid and alkali resistant conveyor belts. The skeleton material adopts EP canvas, which has more reliable acid and alkali resistance than cotton canvas core tape.
