PE Polyethylene
PE Polyethylene is a thermoplastic used in a wide range of products. It takes its name from ethylene in monomer form. In the plastics industry, the name is generally used as PE. The ethylene molecule C2H4 consists essentially of two CH2 connected by double bond. (CH2 = CH2) The production of polyethylene is by polymerization of ethylene. The polymerization method may be by radical polymerization, anionic polymerization, ion coordination polymerization and cationic polymerization methods. Each of these methods produces different types of polyethylene.
Classification of Polyethylene:
Polyethylene is classified into various categories based on density and chemical properties. Its mechanical properties depend on its molecular weight, crystal structure and branching type. UHMWPE (ultra high molecular weight PE)
HDPE (high density PE)
HDXLPE (high density cross-linked PE)
PEX (cross-linked PE)
MDPE (medium density PE)
LDPE (low density PE)
LLDPE (linear connected low density PE)
VLDPE (very low density PE)
Polyethylene Properties:
Although it varies according to the numbers; general characteristics such as good environmental resistance and good resistance to moisture, flexibility, weak mechanical strength and superior chemical resistance. Containers, plastic boxes, kitchen utensils, coatings, pipes and tubes, toys, cables, insulation sheets, packaging and packaging film is a very common use. Low cost.
