Application:

1,6 hexanediol is a major fine chemical material, and has been widely used in polyurethane, polyester, coil coatings, photocuring agents, etc., and is known as a new cornerstone of organic synthesis.

1) Polyurethane field: Polyurethane elastomer is widely used in synthetic rubber, elastic fiber, synthetic leather and other fields. 1,6-hexanediol can be applied to a polyester resin for modifying a polyurethane elastomer. The modified resin is excellent in mechanical strength, water resistance, heat resistance, and oxidation resistance.

2) Polyester field: Since the 1,6-hexanediol unsaturated polyester carbon chain is more difficult to hydrolyze than other short-chain alcohol unsaturated polyesters, and has better flexibility, it can improve the alkali resistance of the resin and improve Its adhesion to fiberglass. In the case of a saturated polyester, a polyester obtained from 1,6-hexanediol and 4,4-dicarboxylic acid-diphenylsulfonic acid has high tensile strength and high elasticity. Excellent solvent resistance and swell resistance, especially suitable for photographic film base. Polyesters of 1,6-hexanediol and terephthalic acid are suitable for the treatment of polyester fibers.

3) Synthetic resin additives: Plasticizers using 1,6-hexanediol have excellent performance in resistance to volatility, spray blasting, migration resistance, and low temperature resistance compared with low molecular weight plasticizers. It can be widely used in plastics, rubber, epoxy resin and other materials.
