Turning to the PE technology market, there are four types of PE production processes that are currently used, distinguished by the way in which ethylene is polymerised: gas phase (for instance UCC, BP, Montedison); slurry (for instance Phillips Petroleum, Mitsui); solution (for instance Novacor, Dow) and high pressure (for instance, ICI, Enichem).
Pour ce qui est de la technologie du PE, on utilise actuellement quatre types de procédés de production du PE, qui se caractérisent par le mode de polymérisation de l'éthylène: la phase gazeuse (ex.: UCC, BP, Montedison), l'émulsion (ex.: Phillips Petroleum, Mitsui), la solution (ex.: Novacor, Dow) et la haute pression (ex.: ICI, Enichem).
