HDPE
High density Polyethylene (HDPE): is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of ethylene and a small amount of α-olefin monomer. HDPE is synthesized under low pressure and is therefore also called low-pressure polyethylene. HDPE is mainly a linear molecular structure and has little branching. It has a high degree of crystallization and high density. It can withstand high temperatures and has good rigidity and mechanical strength and anti-chemical corrosion.
Properties:
High density polyethylene for non-toxic, tasteless, no smelly white particles, melting point is about 130 ° C, relative density of
0.941 ~ 0.960. It has good heat resistance and cold resistance, chemical stability, but also has high rigidity and toughness, good
mechanical strength. Dielectric properties, environmental stress cracking resistance sex also is good.

3.Application:
1.Film grade is widely used in the production of packing bag, film and so on.
2.Blow molding grade for making various bottles, cans, tanks , barrels Injection-molding grade is for making food cases, plastic
trays, goods containers.
3.Blow film product:Foodstuff packing bag,groceries shopping bags, chemical fertilizer
lined with film, etc
4.Extruded product: Pipe,tube mainly used in gas transportation, public water and chemicals
transport, such as building materials, gas pipe, hot water drain pipe etc: sheet material is
mainly used in the seat, suitcase, handling containers.
