 Polyethylene
is produced by polymerization of ethylene (gas) under increased
temperature and pressure conditions. The process requires energy and
unpolymerized ethylene is emitted during the processes. The output of
the process is polyethylene granulate, which is used as a raw material in
the manufacturing of polyethylene products. Ethylene is produced from
oil or natural gas feed stocks. Additives such as colorants and and
plasticizers may be added to obtain desired properties for the end product.
