High density polyethylene (HDPE), white powder or granular product. Non-toxic, tasteless, crystallinity of 80% ~ 90%, softening point of 125 ~ 135ºC, use temperature up to 100ºC; The hardness, tensile strength and creep properties are better than those of LDPE. Good wear resistance, electrical insulation, toughness and cold resistance; Good chemical stability, at room temperature, insoluble in any organic solvent, acid, alkali and various salts corrosion; The membrane has low permeability to water vapor and air and low water absorption. Poor aging resistance, environmental stress cracking resistance is not as good as low density polyethylene, especially thermal oxidation will make its performance decline, so the resin must be added to the antioxidant and ultraviolet absorbent to improve the lack of this aspect. High density polyethylene film has low thermal deformation temperature under stress, so attention should be paid to its application.
Acid and alkali resistance, organic solvent resistance, excellent electrical insulation, low temperature, still can maintain a certain toughness. Surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, tougher than PP, but the surface finish is not as good as PP.
Poor mechanical performance, poor air permeability, easy deformation, easy aging, easy to brittle, brittle than PP, easy to stress cracking, low surface hardness, easy to scratch. Difficult to print, printing, need to carry out surface discharge treatment, can not electroplate, surface dull.
Used for extruding packaging film, rope, woven bag, fishing net, water pipe; Injection molding low-grade daily necessities and shells, non-load-bearing components, plastic boxes, turnover boxes; Extrusion blow - molded containers, hollow products, bottles.
