It is the basic material for producing PBT plastics and fiber, and PBT is one of the five most promising engineering plastics.2. 1,4-butanediol is the main raw material for producing THF, which is an important organic solvent. The polymeric compound PTMEG of THF forms the basic material for highly-elastic urethane elastic fiber, which is mainly used for producing high-grade sports wear and swimming suit that requirs high elasticity.3. 1,4-butanediol is the main material for producing  γ-butyrolacton, which is widely used in pesticide, pharmaceuticals, cosmetics and other industries due to its ability to produce 2-pyrrolidone, NMP and their derivatives NVP and PVP etc. high add-ons products.4. 1. 1.Product 1,4-Butanediol 2.CAS 110-63-4 3.Chemical formula C4H10O24.Appearance Transparent micro viscous liquid Description 1.Product 1,4-Butanediol 2.CAS 110-63-43.Chemical formula C4H10O24.Appearance Transparent micro viscous liquid5.
