What is 1,4-Butanediol
The compound 1,4-butanediol — which is also known as 1,4-B, BD, BDO, butylene glycol, or CAS No. 110-63-4 — is a commodity building block chemical used in polymer and THF production. Each year, more than 2.5 million tons of polymers are manufactured where BDO is employed. BDO can also be used as a chain-extender for urethane systems and as a raw material for other chemical production. BDO is a valuable chemical to the solvent and adhesive industries.

USES AND APPLICATIONS FOR 1,4-Butanediol
1,4-Butanediol uses include cleaning compounds, cosmetics, eye liner, eye shadow, ink, plasticizer, polyester polymers, polyurethanes, solvent, THF, and urethane polymers.
Polyurethanes: 1,4-Butanediol is used in both the hard and soft segments. In the hard segment as a chain extender and in the soft segment as polyesterdiols such as polybutylene adipate glycol. In addition to its use in the soft segments of polyurethanes, 1,4 BDO is used in the hard segments of some polyurethanes, particularly those made with MDI or TDI. In the hard segment or as a crosslinker, 1,4 BDO produces a good balance between hardness and low temperature flexibility
Esters: These esters include monomeric plasticizers, the engineering plastic polybutylene terephthalate (PBT) and low molecular weight polyester glycols. The polyester glycols are used as soft segments in polyurethanes and are made by reacting 1,4 BDO with various dibasic acids such as adipic and sebacic acid.
Organic compound and colorless viscous liquid. It is one of four stable isomers of butanediol.
