 HDPE is a white powder or granular product. Non-toxic, tasteless, crystallinity of 80%-90%, softening point of 125-135℃, use temperature up to 100℃; hardness, tensile strength and creep are better than low density polyethylene; abrasion resistance, electrical insulation, toughness and cold resistance are better; chemical stability is good, at room temperature, insoluble in any organic solvent, resistant to corrosion of acid, alkali and various salts; film permeability to water vapor and air It is less resistant to aging and less resistant to environmental stress cracking than low-density polyethylene, especially thermal oxidation will cause its performance to decline, so the resin must be added with antioxidants and ultraviolet absorbers to improve the deficiencies in this regard, and high-density polyethylene film has a lower heat deflection temperature under stress.








[Basic properties]
High density polyethylene is an opaque white waxy material, lighter than water specific gravity, specific gravity of 0.941~0.960, soft and ductile, but slightly harder than LDPE, also slightly able to stretch, non-toxic, tasteless.
[Combustion characteristics]
flammable, from the fire can continue to burn, the upper end of the flame is yellow, the lower end is blue, burning will melt, there is liquid dripping, no black smoke, at the same time, emit the smell of paraffin burning.
[Main advantages]
Acid and alkali resistance, resistance to organic solvents, good electrical insulation, low temperature, can still 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.To better ensure the safety of your goods, professional, environmentally friendly, convenient and efficient packaging services will be provided.
