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

• PBT (Polybutylene terephthalate) Resin Raw Material

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.

• Polyurethane Resin Raw Material

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.

• Other Polyester Raw Materials

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.
