Factory Price Virgin HDPE/LLDPE Granules High Density Polyethylene

HDPE is a white powder or granular product. Non-toxic, tasteless, crystallinity was 80% ~ 90%, softening point is 125 l ~ 35 ℃, using temperature is 100 ℃; Hardness, tensile strength and creep are better than low density polyethylene. Good wear resistance, electrical insulation, toughness and cold resistance; Good chemical stability, at room temperature, insoluble in any organic solvents, acid, alkali and various kinds of salt corrosion resistance; The film has little permeability to water vapor and air and low water absorption. Aging resistance, environmental stress cracking resistance is better than low density polyethylene, especially hot oxidation will make its performance degradation, so must be added in the resin antioxidant and uv absorber, etc to improve the deficiency of. The heat deformation temperature of high density polyethylene film is low under stress.
