Bio-based PolyTHF is based on renewable raw materials

BASF now offers bio-based PolyTHF 1000.
BASF has made bio-based Polytetrahydrofuran 1000 (PolyTHF 1000) available to selected partners for testing. It is identical in quality to the petrochemical-based product, said Andrej Brejc, director Renewable Diols, BASF's Intermediates division.

PolyTHF is derived from 1,4 butanediol (BDO), which the company has produced under licence from Genomatica.

PolyTHF is primarily used to make elastic spandex fibres for textiles, including underwear, outerwear, sportswear and swimsuits. PolyTHF 1000 is mainly applied as a chemical building block for thermoplastic polyurethane (TPU), used, for example, in parts of ski boots and skates, shoe soles and instrument panel skin for automotives, as well as hoses, films and cable sheathing. It is also used as a component of thermoplastic polyetheresters and polyetheramides. Other applications include cast elastomers, which are used, for example, for the production of wheels for skateboards and inline skates.
