Polyethylene is a polymer consisting of long chains of the monomer
Polyethylene is the most popular plastic in the world.For such a
versatile material, it has a very simple structure, the simplest of all
molecule of polyethylene is nothing more than a long chain of carbon
atoms, with two hydrogen atoms attached to each carbon atom.
Polyethylene with molecular weights of three to six million is referred
to as ultra-high molecular weight polyethylene, or UHMWPE.
Polyethylene is a highly durable material that provides exceptional
engineering characteristics in applications where ease of cleaning,
stability, impact, wear, UV and weather resistance is desirable.
Polyethylene is classified into several different categories based
mostly on its density and branching. The mechanical properties of PE
depend significantly on variables such as the extent and type of
branching, the crystal structure and the molecular weight.
Polyethylene can be processed into various consumer products using
processing techniques such as profile extrusion, film extrusion,
injection molding, blow molding, rotomolding and etc.
Polyethylene is produced using ethylene as a monomer. For high pressure
polyethylene, the other prime requirement is the peroxide initiator.
first commercial polyethylene was produced under very high pressure (~
3,000 atm). This is a free radical reaction process which produces
low-density polyethylene (LDPE) with narrow molecular weight
is now produced by catalytic polymerisation of ethylene in either slurry
(suspension), solution or gas phase reactors. Alpha-olefin comonomers,
such as butene, hexene and octene, may be incorporated at low levels to
modify the polymer's properties.
density polyethylene, Linear medium density polyethylene and medium
density polyethylene resins are used in the production of flexible food
packaging, a shrink-wrap, stretch film and overwrap film.
density polyethylene resins are used in the production of industrial
drums, children's toys and pressure pipes.
Polyethylene demand growth in Asia/Pacific is robust, projected to
continue at rates significantly.
Worldwide LLDPE demand growth is forecast to average ~13%/yr, with
consumption reaching ~14 million metric tons.
wide use of polyethylene makes it an important environmental issue.
Though it can be recycled, most of the commercial polyethylene ends up
in landfills and in the oceans. Polyethylene is not considered
biodegradable, as it takes several centuries until it is efficiently
