LDPE (high pressure Low Density Polyethylene) : the relative Density of 0.910 0.925 Polyethylene as Low Density Polyethylene (Low Density Polyethylene).Low density polyethylene wax is a feeling of white resin, its structure is characterized by nonlinear. Molecular weight is in commonly 100000 ~ 100000. It has a lower crystallinity and softening point, has good flexibility, elongation, electrical insulation, transparency, and high impact resistance strength, low density polyethylene with poor mechanical strength, heat resistance is poor, and the other is an obvious weakness environmental stress cracking resistance is poor.

Most of the low density polyethylene used as film products, and most of the film products used for packing. One part was used for agricultural film and architectural membrane.
