Product Description
The belt carcass of this product is EP fabric(D.S.EP or CC56) of high modulus,low shrink,and high breaking tensile strength.Cover rubber of this product uses SBR, CR, EPDM rubber or Chloroprene rubber that has very good high temperature resistance.The belt is made with extra care after mixing rubber with high temperature resistant materials, assembling and vulcanizing.
The carcass of this product has very high adhesion after the special treatment of coating and shaping.Under normal working temperature of below 180ºC, the belt is low in elongation, excellent in anti-abrasion,and can bear 250ºC(in the cooling condition, 300ºC-600ºC) high temperature for a short time.The belt is suitable for use in cement,metallurgical and steel industry.
