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.

Storage and Handling

14BG is hygroscopic and will be degraded by oxygen, so the storage container should be sealed with dry nitrogen.  It is recommended that storage be at 25-40.  Below 20 14BG will be solid, but can be mellted by careful heating.  To melt solidified 14BG in drums, hold overnight at 50-70.  Volatility is low, and 14BG is unlikely to catch fire by itself at room temperature.  However, in case it is burning, dry chemical, foam (alcohol resistant), or large amounts of water are effective.  14BG has relatively low toxicity and is a relatively safe chemical.  When handling, however, protective equipment such as protective gloves and goggles should be worn.
