Good stress cracking resistance: HDPE drainage pipe has low notch sensitivity, high shear strength and excellent scratch resistance, and its ability to resist environmental stress cracking is also very outstanding; good chemical resistance: HDPE drainage pipe can withstand more Corrosion of a chemical medium, the chemicals in the soil will not cause any degradation to the pipeline. Polyethylene is an electrical insulator, so it will not rot, rust or electrochemically corrode; in addition, it does not promote the growth of algae, bacteria or fungi; anti-aging, long service life: contains 2-2.5 percent evenly distributed carbon black Polyethylene pipe can be stored or used outdoors for 50 years without damage from UV radiation.
