This belt features excellent elasticity, troughability, impact, cut, tear, flex and moisture resistance. Built with integrated high‑impact steel cord mesh carcass, optimized rubber compound and integral calendering coating construction, it uses finger‑type splicing for smooth roller passage and bidirectional operation. Its lighter carcass weighs only around 80% of conventional tear‑resistant steel cord belts, helping reduce energy consumption during long‑term operation.
