HDPE Pipe and HDPE Pipe Fittings

• HDPE has good heat resistance and cold resistance, good chemical stability, high rigidity and toughness and good mechanical strength.
• Dielectric properties and environmental stress cracking resistance are also good.
• The hardness, tensile strength and creep are better than those of LDPE.
• Wear resistance, electrical insulation, toughness and cold resistance are good, but slightly worse than low density insulation.
• Good chemical stability, at room temperature, insoluble in any organic solvent, resistant to acid, alkali and various salt corrosion.
• The membrane has low permeability to water vapor and air and low water absorption.
• The aging resistance is poor, and the environmental cracking resistance is not as good as that of LDPE, especially the thermal oxidation will reduce its performance. Therefore, antioxidant and ultraviolet absorbent should be added to improve the resin.
• The hot deformation temperature of HDPE film under stress is lower, which should be paid attention to in application.
