Ludwigshafen/Germany – BASF also took measures to modernize and enhance the efficiency of its plants and ensured the supply of the raw materials it needs to manufacture PolyTHF. All in all, BASF invested more than 60 million euros.

BASF started up its first plant manufacturing PolyTHF at its integrated Verbund site in Ludwigshafen in 1983. Today BASF as an global supplier of PolyTHF supports its customers’ growth in all regions with local manufacturing capabilities at its sites in Geismar, Louisiana, USA; Ludwigshafen, Germany; Ulsan, Korea; and Caojing, China.

„Asia/Pacific Region, the World’s Major PolyTHF Market Today“

Especially the plants in Ulsan and Caojing become more and more important. “Growth rates at our customers and in our business are highest in the Asia/Pacific region, the world’s major PolyTHF market today”, said Sanjeev Gandhi, President, BASF Intermediates division.

PolyTHF is primarily used to make elastic spandex fibers for a large variety of textiles, including underwear, outerwear, sportswear and swimsuits. It also serves as a chemical building block for thermoplastic polyurethanes (TPU) used to make hoses, films and cable sheathing. Other applications include thermoplastic polyetheresters, polyetheramides and cast elastomers for the production of wheels for skateboards and inline skates.
