Coal and material storage liner surfaces are smooth and shiny, evenly bearing loads, capable of withstanding high impact forces, with stable mechanical properties, resistant to bending and deformation. They feature high mechanical strength, low tendency to deform, low water absorption rate, small density, high tensile strength, and are not prone to cracking. Mainly used for fender boards at ports and harbors, coal and material storage liners, and in industries such as construction machinery.
