Polypropylene (or PP for short) belongs to the polyolefin family and is the most widely used plastic in Europe in terms of quantity. This is due to its flexible areas of application, the low price of the raw material and its good processability. Its very low density together with good strength values and easy handling also make PP a very attractive starting material for fibre production. As pure polypropylene is very susceptible to oxidation from atmospheric oxygen, UV and thermal stabilisers are added during the manufacturing process. The polypropylene fibre materials offered by STW are manufactured using the melt spinning process.
Polypropylene is manufactured using organometallic catalysed polymerisation. Either the Ziegler-Natta catalysts (named after their inventors) or the somewhat more recent metallocene catalysts are used here. Depending on the catalyst used and the required property profile, isotactic or syndiotactic polypropylene can be produced. The good and easy processability of polypropylene allows a variety of fibre production options. Primarily, a variety of melt spinning techniques are used. Fibres based on the film-to-fibre or meltblow process are also available.
