Polypropylene (PP) is a thermoplastic polymer made by polymerization of propylene. It is used in a wide variety of applications including food packaging, ropes, textiles, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components and polymer banknotes.
Isotactic, syndiotactic and atactic polypropylene are distinguished from one another, depending on the position of the methyl groups relative to the polymer chain. Various polymerization processes have been developed which can be run in bulk loop / gas phase (Spheripol®, Borstar®) or in the gas phase alone (Unipol™ PP, Novolen®, Innovene™ PP, Horizone PP). The end use of the polypropylene will ultimately decide the route required to achieve the desired properties. The various types of polypropylene, for example, homopolymer, impact copolymer or random copolymer will use a variety of catalyst components which are heavily dependent upon the licensed process in use.Product portfolio
