It can be safely used in the temperature range of -60-60 degrees Celsius, and the pipe will not be brittle due to the good impact resistance of the material during winter construction.
HDPE is a thermoplastic resin with high crystallinity and non-polarity. High-density polyethylene is a non-toxic, tasteless and odorless white particle, with a melting point of about 130 degrees Celsius and a relative density of 0.941~0.960. It has good heat and cold resistance, good chemical stability, high stiffness and toughness, and good mechanical strength. Dielectric properties and environmental stress cracking are also good. The melting temperature is 220~260 degrees Celsius. For materials with large molecules, it is recommended that the melting temperature range is between 200~250 degrees Celsius. High-density polyethylene is a non-toxic, odorless white powder granular product with a density of 0.940~0.976g/cubic centimeter; The crystallinity is 80%~90%, the softening point is 125~135 degrees Celsius, and the service temperature can reach 100 degrees Celsius; Hardness, tensile strength and creep are better than those of low-density polyethylene; It has good wear resistance, electrical insulation, toughness and cold resistance, but is slightly inferior to low-density insulation.
