features
High density polyethylene (HDPE), white powder or granular product. Non-toxic, tasteless, crystallinity of 80% ~ 90%, softening point of 125 ~ 135℃, use temperature up to 100℃; 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.


High density polyethylene
High density polyethylene is an opaque white waxy material, the proportion of light than water, the proportion of 0.941~0.960, soft and tough, but slightly harder than LDPE, also slightly elongated, non-toxic, tasteless. Acid and alkali resistance, organic solvent resistance, excellent electrical insulation, low temperature, still can maintain a certain toughness. Surface hardness, tensile strength, rigidity, etc
Range of application
Used for extruding packing 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.
