Product Features

High density polyethylene has good heat and cold resistance, good chemical stability, high rigidity and toughness, and good mechanical strength. Dielectric properties, environmental stress cracking resistance is also good. The hardness, tensile strength and creep properties of low density polyethylene are better than those of low density polyethylene. Good wear resistance, electrical insulation, toughness and cold resistance, but slightly worse than low density insulation; Good chemical stability, at room temperature, insoluble in any organic solvents, acid, alkali and all kinds of salt corrosion resistance; Thin film to water vapor and air permeability is small, low water absorption; The aging resistance is poor, the environmental cracking resistance is not as good as low density polyethylene, especially the thermal oxidation will reduce its performance, so the resin needs to add antioxidants and ultraviolet absorbent to improve this aspect of the deficiency. The thermal deformation temperature of high density polyethylene film under stress is low, which should be paid attention to when applied.
