LDPE (high pressure low density polyethylene):
Non-toxic, tasteless, odorless, translucent spherical or cylindrical particles, excellent low temperature resistance,
chemical resistance, good extensibility, electrical insulation, but poor wetness, Flammable.
Density: 0.910—0.9408g/cm³, suitable for extrusion, blister, injection molding, vacuum, molding, and conversion
molding and other processing methods. The crystallinity is 55-65%, and the crystal melting point is 108-126 °C.
