Polyethylene (abbreviated PE) or polythene (IUPAC name polyethene or poly(methylene)) is the most common plastic. The annual production is approximately *0 million metric tons. Its primary use is within packaging (plastic bag, plastic films, geomembranes, containers including bottles, etc.). Many kinds of polyethylene are known, with most having the chemical formula (C2H4)nH2. Thus PE is usually a mixture of similar organic compounds that differ in terms of the value of n.
Physical properties
Polyethylene is a thermoplastic polymer consisting of long
hydrocarbon chains. Depending on the crystallinity and molecular
weight, a melting point and glass transition may or may not be
observable. The temperature at which these occur varies strongly
with the type of polyethylene. For common commercial grades of
medium- and high-density polyethylene the melting point is
typically in the range **0 to **0 celsius. The melting point for
average, commercial, low-density polyethylene is typically **5 to
**5 celsius
Chemical properties
Most LDPE, MDPE and HDPE grades have excellent chemical resistance,
meaning that it is not attacked by strong acids or strong bases. It
is also resistant to gentle oxidants and reducing agents.
Polyethylene burns slowly with a blue flame having a yellow tip and
gives off an odour of paraffin. The material continues burning on
removal of the flame source and produces a drip. Crystalline
samples do not dissolve at room temperature. Polyethylene (other
than cross-linked polyethylene) usually can be dissolved at
elevated temperatures in aromatic hydrocarbons such as toluene or
xylene, or in chlorinated solvents such as trichloroethane or
trichlorobenzene.
