What are you looking for?
Acid and alkali resistant conveyor belts are suitable for working environments that are in contact with acids and alkalis, such as phosphate fertilizers manufacturing, sea water salting. They are typically designed to convey acid and alkali based materials in the chemical and industrial applications. The belt consists of a top and bottom cover made of highly acid and alkali resistant rubber as well as a carcass made of nylon or polyester canvas.
Acid and alkali resistant conveyor belt features excellent flexibility, small elongation rate, and good troughability for a wide range of applications. As one of the most professional acid-alkali resistant conveyor belt manufacturers, Rentone Belt can supply a variety of acid-alkali resistant conveyor belts of high quality and best price in different width, length, and specifications as per customer’s requirements.
