HDPE Material
Properties:
High density polyethylene for non-toxic, tasteless, no smelly white particles, melting point is about 130℃, 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 also good.
Application:
1: HDPE 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 , barrel, 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.
