High-density polyethylene commercial introduction

It is important to understand that the introduction of linear low-density polyethylene (LLDPE) in the 1960s and late 1970s, manufactured by the solution process and the gas-phase process, both operating at relatively low pressure utilizing a transition metal-based catalyst, provided a new type of polyethylene with unique properties that did not result in the elimination of the high-pressure process from commercial use. It opened new markets and applications for the polyethylene industry and resulted in its continued rapid growth.
