Polyethylene (PE) and Polypropylene (PP)


Polyethylene (PE) and Polypropylene (PP) are produced through processes that polymerise ethylene and propylene molecules into long molecular chains using catalysts.

Small amounts of comonomers are often added to give the PE/PP unique physical properties. A number of different production processes exist to make PE/PP, with some general similarities:

Raw materials including feedstock monomers, comonomers and catalysts have to be purified or refined to eliminate minute amounts of impurities that affect the process, such as water (H2O), oxygen (O2), carbon monoxide (CO), carbon dioxide (CO2) and carbonyl sulfide (COS).
