Top and bottom cover adhesive thickness, mm

Primarily used in long-distance conveying systems for metallurgy, mining, coal, ports, power generation, and the chemical industry.

Features

This product is composed of core rubber, steel cables, a cover layer, and sidewall rubber. Based on the performance of the cover rubber, it can be categorized into types such as standard, flame-retardant, heat-resistant, abrasion-resistant, cold-resistant, acid-alkali resistant, and oil-resistant varieties. It boasts high tensile strength, excellent impact resistance, long service life, minimal elongation during use, outstanding groove-filling properties, superior flex resistance, and advantages like efficient material handling over long distances, high transport capacities, and fast-speed conveyance.
