Wear-resistant PVC 3d wall panels, also called ultra-high molecular weight polyethylene (UHMWPE), are currently one of the most widely-produced and widely-used plastics, accounting for about 30% of the world’s total plastic production. Among them, LDPE, HDPE and the third LLDPE and other substitutes for polyethylene are all thermoplastic general-purpose plastics.
Only ultra-high molecular weight polyethylene (UHMEPE) with a molecular weight of more than 1.5 million is used as an engineering plastic because of its excellent physical and mechanical properties. Wear-resistant plastic board performance: Wear resistance UHMWPE has the highest wear resistance of plastics and surpasses certain metals. Compared with other engineering plastics.
Such high abrasion resistance makes it difficult to test the wear resistance level with the ordinary plastic abrasion test method, so a mortar abrasion test installation is specially designed. The wear resistance of UHMWPE is directly proportional to the molecular weight. The higher the molecular weight, the better the wear resistance. Impact resistance The impact strength of UHMWPE.
Among all engineering plastics, the impact strength of UHMWPE is about 2 times that of impact-resistant PC, 5 times that of ABS, and more than 10 times that of POM and PBTP. The impact resistance is so high that it is difficult to break and destroy it by the usual impact test methods. Its impact strength increases with the increase of molecular weight.
