Polyethylene is the most common plastic in the world.
Currently, more than 100 million tons of various types of polyethylene are produced.
The main area of production is the manufacture of packaging (plastic bags, plastic films, bottles, etc.).
Polyethylene has low strength, hardness and stiffness, but has high ductility and toughness, as well as a low coefficient of friction.
The commercial applicability of polyethylene is limited by its relatively low melting point. For ordinary commercial grades of medium and high density polyethylene, the melting point is usually in the range from 120 to 180 ° C. The melting point for medium industrial low density polyethylene is usually from 105 to 115 ° C. These temperatures vary greatly depending on the type of polyethylene.
Polyethylene almost does not absorb water. The gas permeability and water vapor permeability are lower than for most plastics.
PE can become brittle when exposed to sunlight, carbon black is usually used as a UV stabilizer.
Polyethylene is a good electrical insulator. Therefore, it has been widely used in the manufacture of wires and cables.
Polyethylene is classified by density and branching. Its mechanical properties substantially depend on such variables as the degree and type of branching, crystal structure and molecular weight.
There are several types of polyethylene:
Ultra High Molecular Polyethylene (UHMWPE)
Ultra Low Molecular Weight Polyethylene (ULMWPE or PE-WAX)
High Molecular Polyethylene (HMWPE)
High Density Polyethylene (HDPE)
High Density Crosslinked Polyethylene (HDXLPE)
Crosslinked Polyethylene (PEX or XLPE)
Medium Density Polyethylene (MDPE)
Linear Low Density Polyethylene (LLDPE)
Low Density Polyethylene (LDPE)
Very Low Density Polyethylene (VLDPE)
Chlorinated Polyethylene (CPE)
The best-selling brands of polyethylene are HDPE, LLDPE and LDPE, as well as polyethylene wax and its emulsions.
