What is Polyethylene (PE)?

Polyethylene (PE) is a common name for  polymers produced in the methane polymerisation process. Polyethylene (PE) is a thermoplastic, elastic and non-toxic  polymer. It is difficult to ignite and burns with a non-smoky flame. Polyethylene is translucent; it does not solve in all widely used solvents and is resistant to chemical substances such as acids, alkali and saline solutions.

Polyethylene (PE) is an inexpensive industrial raw material. In order to improve Polyethylene (PE) properties, it is modified.

Depending on its density, Polyethylene (PE) is classified into:

• Low-density Polyethylene (LDPE) and Linear Low-density Polyethylene (LLDPE), the density range of which is 910 - 925 kg/m3. 
• Medium-density Polyethylene (LDPE), which is defined by a density range of 925 - 940 kg/m3. 
• High-density Polyethylene (HDPE), the density of which ranges from 940 to 970 kg/m3.

The main indices of Polyethylene are density and the melt flow rate. In order to facilitate the choice of a particular type of Polyethylene, the table below shows the relation between Polyethylene properties and the change in density and the melt flow rate.
