1,4-Butanediol (BDO) is a high-quality intermediate. 1,4-Butanediol and butanediol derivatives are widely used for producing plastics, solvents, electronic chemicals and elastic fibers. N-Methylpyrrolidone is a high-quality specialty solvent that is used to produce coatings, crop protection products, medicines and other products. N-Ethylpyrrolidone is a high-quality intermediate that is used, for example, in the production of crop protection products and in textile finishing.
Gamma-Butyrolactone (gamma-Butyro-1,4-lactone; GBL) is a high-quality intermediate. Most of the GBL quantities produced are used by the chemical industry as an intermediate for the production of specialty chemicals. Moreover, BASF’s customers use GBL for producing crop protection products (fungicides, insecticides). Additional examples are products for beverage filtration and cleaning of circuit boards in the electronics industry.
Tetrahydrofuran (THF) is a high-quality intermediate that serves, for example, as a specialty solvent in the production of medicines.
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), which are used to make hoses, films and cable sheathing. Other applications include thermoplastic polyetheresters, polyetheramides and cast elastomers, e.g., for the production of wheels for skateboards and inline skates.
