Product Discription

Low-density polyethylene (LDPE), polymerized with organic peroxide as initiator under high pressure of 100~300 MPa, belongs to the first generation of polyethylene. So it is also called high-pressure polyethylene. The density of LDPE is generally in the range of 0.910~ 0.925g/cm³. The crystallinity of LDPE is about 5%~65%, and the melting point of LDPE range from 105℃ to 125℃. It has good softness, extensibility, transparency, electrical insulation, air permeability, cold resistance and process-ability. Except those, it also has good chemical stability, resistant to acid, alkali and salt solution.

High density polyethylene (HDPE), produced by ethylene polymerization under low pressure using Ziegler catalyst or metal oxide as catalyst, belongs to the second generation of polyethylene. It is also called low pressure polyethylene. Although it is polymerized by low pressure method, the density of the product in the range of 0.941 ~ 0.965g/cm³ is relatively high. The crystallinity of HDPE is 80% ~ 90% and the melting point range is 126 ~ 137 ℃. The product service temperature can reach 100℃. The mechanical properties such as hardness, tensile strength and denaturation resistance of HDPE are better than those of LDPE, but the time abrasion resistance, electrical insulation, toughness, cold resistance, aging resistance and environmental stress cracking resistance of HDPE are not as good as those of LDPE. High density polyethylene (HDPE) has low water absorption, low permeability to water vapor and air, high crystallinity, warpage and poor impact resistance.
