Product Details

Basic Product Description

The core of the product is polyester canvas with high modulus, low shrinkage and high breaking strength. The covering rubber is made of ethylene propylene diene monomer or chlorinated butyl rubber with good high temperature resistance. It is refined with high temperature resistant materials in conformity with forming and vulcanizing processes. After special impregnation and setting treatment, the product has high bonding strength, small elongation deformation and excellent abrasion performance under normal service conditions below 180 C. Mainly used in metallurgy, construction and other industries, transport sinter, coke, cement clinker and other high-temperature materials.
