Product Information
>> 1,4 BUTANEDIOL (1,4 BDO)
- Process : Davy Mckee (KPT)
- 1,4-Butanediol(also known as its less popular chemical synonyms:1,4-butylene glycol, 1,4- tetramethylene glycol and 1,4-dihydroxybutane ) is a low-viscosity glycol used almost exclusively as an intermediate to synthesize other chemicals and polymers.
The butanediol molecule maintains its original chemical identity only when used as as a solvent. Since butanediol can undergo the typical reactions of a primary alcohol, it lends itself to a very large number of chemical modifications. As it is a difunctional molecule, most of its use is in the area of polymers, such as
polyurethanes(prepolymers, cast elastomers, thermoplastic elastomers, reaction injection molding, and fibers such as spandex), polybutylene terephthalate(PBT), a large family of homopolymers and copolymers of N- vinyl-2-pyrrolidone, and copolyester-ether thermoplastic elastomer(COPE). - Production Capacity : 28,000 MTA
