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 180℃, the belt is low in elongation, excellent in anti-abrasion, and can bear 250℃(in the cooling condition, 300℃-600℃) high temperature for a short time. The belt is suitable for use in cement, metallurgical and steel industry.

Characteristic:

Be conducted by cotton canvas or polyester canvas of high content of cotton and cover rubber of heat resistant.

Advantages and Usage

Be used to convey hot materials or elevated temperature materials such as metallurgy, casting, coking,building material, chemical and so on. Because the cover rubber is of a certain heat resistance.
