Polyethylene Low Density Plastic (LDPE)

LDPE (low density polyethylene) plastic Raw material granules

Description:

LDPE (Polyethylene)

LDPE is a milky translucent waxy solid resin, non-toxic. Softening point is lower, Above it will be thaw, the hot melt connection, forming performance is good, good flexibility, impact toughness, low temperature resistance is good, but in **0°C ~ **0°C, good electrical insulation.

The physical and chemical properties:

PE material classification:

( 1): LDPE low density polyethylene, high pressure polyethylene ( 2) LLDPE: linear low density polyethylene

( 3): MDPE medium density polyethylene resin, Shuangfeng ( 4) HDPE: high density polyethylene, low pressure polyethylene 

The LDPE poor mechanical strength, heat resistance, resistance to environmental stress cracking resistance, adhesion, adhesion, poor printability, subject to surface treatment, such as chemical erosion, corona treatment before it can improve its adhesion, printing.

The LDPE absorbent is very low, almost no water absorption, chemical stability good, such as acid, alkali, salt, organic solvents are more stable. On CO2, organic odor permeability, but the water vapor, air permeability. Easy burning, burning like a wax;

The LDPE in the sunlight and heat effect easy degradation and color, from white to yellow to brown, the final was black, and performance degradation or cracking, if adding a certain amount of antioxidants, ultraviolet absorbers can improve performance, in the chemical crosslinking agent or high-energy radiation crosslinking, can provide high softening point, heat resistance, stiffness, solvent resistance.
