Steel cord conveyor belt-Hebei Ssangyong Rubber Co.,Ltd

Function introduction

Features: high tensile strength, good impact resistance, long life, low elongation in use, good groove formation, and good bending resistance. Suitable for long-distance, large-volume, and high-speed transportation of materials. The product is composed of core rubber, steel wire mesh, covering layer and edge rubber.

Uses: Widely used in coal, mines, ports, metallurgy, electric power, chemical industries and other fields to transport materials.

Variety: According to the performance of the covering rubber, it can be divided into: ordinary type, flame retardant type, heat-resistant type, cold-resistant type, acid-base resistant type, oil-resistant type and other varieties.
