|
LDPE means Polyethylene with low density; HDPE means Polyethylene with high density. Physicochemical properties vary depending upon the molecular mass.
Thermal degradation starts at 290°C.
The PE products are available in large selection of various forms, due to additives used in the manufacture.The additives can influence the physical and toxicological properties of this substance.
