High density Polyethylene (HDPE): is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of ethylene and
a small amount of a-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 lttle 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.
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.
Used in water conservancy projects, rivers, tunnels and other fields.
Film grade is widely used in the production of packing bag, film and so on.
Blow molding grade for making various bottles, cans, tanks,barrels.
Injection-molding grade is for making food cases, plastic trays, goods
containers.
Blow film product:Foodstuff packing bag,groceries shopping bags,chemical fertilizer lined with film, etc
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.
