Ultra high density polyethylene sheets Technology
Ultra high density polyethylene sheets are the perfect engineering plastic product that combines wear resistance, self-lubrication and impact resistance in engineering plastics at present. It has many properties unmatched by other plastics.Tangyin Xinxing provides you more detailed introduction of UHMWPE sheet products.
Ultra high density polyethylene sheets refers to polyethylene with a relative molecular weight of more than 6 million. The relative molecular mass of ultra high molecular weight polyethylene produced by some foreign companies has reached more than 6 million. Although its molecular structure arrangement is exactly the same as ordinary polyethylene, but because it has a very high relative molecular mass (relative molecular weight of ordinary polyethylene is only 200,000 to 300,000), it gives him many unparalleled resistance to ordinary polyethylene. Grinding, impact resistance, corrosion resistance, low temperature resistance, self-lubrication, impact energy absorption and sanitary non-toxicity are widely used in chemical, petroleum, textile, paper, packaging, transportation, machinery, mining, agriculture, construction, electrical, Food, medical, sports and other fields are a new type of engineering plastic with excellent performance.
Ultra high density polyethylene sheets molding process:
As a thermoplastic engineering plastic, UHMWPE has excellent comprehensive properties in the solid state, but its melt characteristics are completely different from those of ordinary thermoplastics such as ordinary polyethylene, which brings difficulties to processing. Generally, compression molding is used in China for a variety of plastics. Molding and compression molding are characterized by low cost, simple equipment, low investment, and are not affected by the relative molecular weight of UHMWPE. Even UHMWPE with high molecular weight in the world can be processed. Because its relative molecular weight is too high and its fluidity is poor, in the case of other molding processes that are not yet mature, countries around the world use compression molding to process UHMWPE products.
