Polypropylene is a downstream petrochemical product derived from the olefin monomer, propylene. The polymer is produced through a process of monomer connection called addition polymerization, normally by using the Ziegler-Natta catalyst system.
Polypropylene properties can be tailored including process conditions, copolymer components and contents, molecular weight and molecular weight distribution.
Isotactic polypropylene is well suited for a variety of end uses, ranging from flexible and rigid packaging to fibres and large moulded parts for automotive and consumer products.
Polypropylene is recyclable, an important consideration in many packaging and automotive applications, and it can be incinerated without toxic emissions.
It can be processed using most methods including cast, blown and BOPP film extrusion, extrusion coating, blow moulding and injection stretch blow moulding, injection moulding and thermoforming. Its physical properties can be easily enhanced through additives.
Polypropylene has excellent chemical resistance and electrical insulating properties.
