1,4-Butanediol (1,4-BDO) is a colourless at room temperature viscous liquid or white solid (depending on temperature). 1,4-BDO is used in both the hard and soft segments of Polyurethanes, in the hard segment as a chain extender and in the soft segment as polyesterdioles such as polybutylene adipate glycol.
1,4-BDO is used to make a variety of esters, including 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.
