High density polyethylene (HDPE) is a kind of highly crystalline non-polar synthetic resin formed by copolymerization of ethylene and a small amount of -olefin monomer. It is synthesized under low pressure, so it is also called low pressure POLYETHYLENE. Its molecular structure is mainly linear structure, less branch chain in the molecule, high crystallinity, high density, high temperature, hardness and mechanical strength, good chemical resistance.The product is white transparent granular, belongs to general plastic products, widely used. Hdpe can be used in a variety of plastic molding methods. Hollow blow molding method can be used to make all kinds of bottles, cans and industrial tanks, barrels and other containers; Injection molding production of various basins, buckets, baskets, baskets and other daily containers, daily groceries and furniture; Extrusion molding production of all kinds of pipe, ribbon and fiber, monofilament, etc.; Also can be used to make wire and cable coating materials and synthetic paper; After adding a large number of inorganic fillers, calcium plastic packing boxes, furniture and doors and Windows can also be made to replace wood and cardboard.QHB18 is fuel tank special material, high molecular weight, rigidity and creep resistance is good, with impact resistance, corrosion resistance, environmental stress cracking and other excellent performance and good processing performance. Exported to domestic and foreign markets.
