High molecular weight ultra high molecular weight polyethylene sheet given its excellent performance coal bin liner wear, and belongs to the affordable, high-performance engineering thermoplastics bunker wear plate manufacturer, which focused almost entirely on the merits of various plastics with ordinary polyethylene and other plastics unmatched wear resistance, impact resistance, self-lubricating, corrosion-resistant, absorbing impact energy, low temperature, non-toxic health, easy adhesion, easy to absorb water, less dense and so overall performance. Ultra high molecular weight polyethylene sheet liner wear such high wear resistance, so that the abrasion test method with the general plastic difficult to test their degree of wear, which designed a mortar abrasion testing device. UHMWPE wear and proportional to molecular weight, the higher the molecular weight, the better the wear resistance.
