Application

1,6-Hexanediol is widely used for industrial polyester and polyurethane production.

- 1,6-Hexandiol can improve the hardness and flexibility of polyesters as it contains a fairly long hydrocarbon chain. In polyurethanes, it is used as a chain extender, and the resulting modified polyurethane has high resistance to hydrolysis as well as mechanical strength, but with a low glass transition temperature.
- It is also an intermediate to acrylics, adhesives, inks and dyestuffs. Unsaturated polyester resins have also been made from 1,6-hexanediol, along with styrene, maleic anhydride and fumaric acid.
