Polyethylene (PE)

Introduction:

Polyethylene (PE) is a light, versatile synthetic resin made from the polymerization of ethylene. Polyethylene is a member of the important family of polyolefin resins. It is the most widely used plastic in the world, being made into products ranging from clear food wrap and shopping bags to detergent bottles and automobile fuel tanks. It can also be slit or spun into synthetic fibres or modified to take on the elastic properties of a rubber.

Polyethylene (PE) in Turkmenistan:

Turkmenistan began the sale of polypropylene (PP) and high-density polyethylene (HDPE) from a new gas chemical complex in the village of Kiyanly (Balkan region, Turkmenistan).
The plant will annually process 5 billion cubic meters of natural gas and produce 386,000 tons of polyethylene and 81,000 tons of polypropylene.
