Application:
1.1,4-butanediol is an important raw materials for organic and refined. 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. 1,4-butanediol is the main material for producing polyurethane artificial leather, polyurethane, elastomer and polyurethane sole glue. polyurethane elastomer are widely used to manufacture elastic sole, auto solid fire, friction conveying belt and etc
