Chemicals
1,4-Butanediol (BDO) and its derivatives (THF/PTMEG) were developed to provide a low cost, highly efficient route to producing spandex fibers. Increasingly, alternative applications of these chemicals are being explored.
For manufacturers, the key to success is low-cost raw materials coupled with world-scale, robust technology delivering advantaged CAPEX and OPEX.
The technologies offered by Koch Technology Solutions deliver against all of these requirements.
Butanediol (BDO) is a key intermediate in the manufacturing supply chain supporting consumer demand for bio-degradable plastics (PBAT), Spandex stretch fabric (PTMEG), fuel-efficient vehicles and lightweight alternatives to steel (PBT) and batteries/fuel cells for electric vehicles (GBL).
Tetrahydrofuran (THF) is a key intermediate in the production of PTMEG. This market currently consumes ~70% of THF produced globally. The remaining THF is used as a solvent used in pharmaceutical production and other markets.
Polytetramethylene ether glycol (PTMEG) is the premium component for a wide variety of polyurethanes, polyesters, and polyamide elastomers. It reacts with isocyanates or organic acids to form elastomers. Primary end-uses include spandex, castable polyurethanes, thermoplastic polyurethanes, polyurethane coatings and sealants.
