14BG/1,4-Butylene glycol/1,4-Butanediol(BDO) CAS 110-63-4
1. Description
14BG (1,4-Butanediol) is a straight chain glycol with hydroxyl groups on both ends. It is used as a raw material for high performance polyester and polyurethane resins as well as for industrial chemicals like tetrahydrofuran and gamma-butyrolactone.
2. Characteristics
14BG (1,4-Butanediol (BDO), 1,4-Butylene glycol (BG), 1,4-Dihydroxy butane, Tetramethylene glycol (TMG)) is the 4-carbon atoms straight-chain glycol (diol, dihydric alcohol) with a hydroxyl groups at both ends.

4. Applications
14BG (1,4-Butanediol (BDO), 1,4-Butylene glycol (BG), 1,4-Dihydroxy butane, Tetramethylene glycol (TMG)) is a raw material for polyester and polyurethane resins (chain extender, hard segment) that show excellent characteristics.
These products find a wide range of applications including everyday consumer products such as clothing and shoe soles, consumer durables such as electrical appliances and cars, industrial materials such as machine parts, as well as medical products. It is anticipated that the use of these polymers will continue to expand.
Main Applications
Because 14BG diol (dibasic alcohol) is used as a raw materail, PBT is a great engineering plastic with low water-absorbance and an excellent balance of mechanical and electrical properties. Applications are expanding beyond the original electrical/electronic parts and automotive parts markets.
By using 14BG diol for the chain extender, urethane elastomers can be made with excellent mechanical properties and high resistances to heat, oil, and impact.
14BG is widely used to make various polyester resins and plasticizers.
Raw Material for Industrial Chemicals (Tetrahydrofuran, Gamma-Butyrolactone)
Tetrahydrofuran and gamma-butyrolactone are produced indutrially by dehydration or dehydrogenation of 14BG.
