HDPE(high-density polyethylene)
High density polyethylene, is a high crystallinity, non-polar thermoplastic resin. HDPE appearance of the original state was milky white, in the meager section of a certain degree of translucent. PE has excellent resistance to most of the characteristics of life and industrial chemicals.
[Basic characteristics] HDPE is an opaque white wax-like material, the proportion of light than water, the proportion of 0.941 ~ 0.960, soft and tough, but slightly harder than the LDPE, but also slightly elongated, non-toxic, tasteless
[Main advantages] acid and alkali resistance, organic solvents, electrical insulation, low temperature, can still maintain a certain toughness. Surface hardness, high tensile strength
[Applications] for extrusion packaging film, rope, woven bags, fishing nets, water pipes; injection of low-grade daily necessities and shell, non-bearing load components, plastic boxes, turnover box; extrusion blow molding containers, hollow products, bottles.
[Product performance]
High density polyethylene is non-toxic, tasteless, odorless white, it has good heat resistance and cold resistance, chemical stability, but also has high rigidity and toughness, good mechanical strength, dielectric properties, environmental resistance Stress cracking is also good.
