Ultra-high molecular weight polyethylene (UHMWPE) and its molecular structure ordinary polyethylene basically the same, but the physical and mechanical properties, but far more than the ordinary polyethylene, such as low-toxic, light weight, low cost, water absorption, with good cryogenic and high temperature performance, at a high temperature may reach 70 ℃ case operation, the internal structure unchanged. Particularly its impact resistance, abrasion resistance, chemical resistance, self-lubricating, absorb impact energy and non-scaling and other characteristics of any other pipe is unmatched. Weather type: polyethylene sheet due to high crosslink density, good stability, artificial ultraviolet irradiation 300 hours, no change in the surface, long service life. Corrosion resistance: resistant to many chemicals, after soaking the basic shape and not cracked, which can use a wide range of chemical pipelines, tank insulation. Low temperature resistance: Under the strong temperature, the material does not destroy the structure, deformation, cracks. Non-toxic: polyethylene sheet does not have any toxic substances. Decompose at high temperatures, it does not produce harmful gases. Cushioning: polyethylene sheet its impact resistance, cushioning best for other insulation materials. Other advantages: beautiful, a variety of colors to choose from; easy processing, easy to comply with other materials; soft and smooth, feel good; light as cotton.
