LDPE-Low density polyethylene
Introduce:
LDPE resins are made by high pressure autoclave process and mainly used for blown film extrusion and wire coating (cable sheath) etc...They are widely used for applications for general purpose packaging films, heavy duty bags, shrink films, and foams.
Properties:
LDPE has good toughness, low temperature resistance, creep, and large thermal expansion.
LDPE is easy to process molding, can be extrusion, blow molding.
