What is Polyethylene (PE)?

Author:

Polyethylene PE 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. Its primary use is in packaging (plastic bag, plastic films, geomembranes, containers including bottles, etc.). Polypropylene (PP) is a thermoplastic polymer linear structure based on the monomer CnH2n. It is manufactured from propylene gas in presence of a catalyst such as titanium chloride. PP is a by-product of oil refining processes. It is used in a wide variety of applications including packaging and labeling, textiles (e.g., ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotives etc.
