Application： It is used in tunnel projects,such as laneway, tunnels, slope protection and shortcrete. It widely apply in Hydropower , mining, military defense fields ,etc.
Inner Layer： Super abrasion resistance,flexibly, anti-adhesion UPE layer
Reinforcement：High tensile synthetic steel cord spiral
Outer Layer： Black SBR synthetic rubber, with high wear resistance and excellent anti-aging performance, wrapped cover
Temperature Range： -30℃ to +85℃
Features：Light weight, easy to operate, with excellent wear resistance performance, The abrasion performance of inside UPE liner is 3-5 times than abrasion resistant rubber, Which with good yield strength performance, more safety for users.
Standard：DIN53516
