Use:
① Polyurethane field: Polyurethane elastomer is widely used in synthetic rubber, elastic fiber, synthetic leather and other fields. 1,6- Hexanediol can be used in polyester resin to modify polyurethane elastomer. The modified resin has excellent mechanical strength, water resistance, heat resistance and oxidation resistance.
② Polyester field: because the carbon chain of unsaturated polyester of 1,6- hexanediol is more difficult to hydrolyze than unsaturated polyester of other short-chain alcohols, and its flexibility is better, it can improve the alkali resistance of resin and improve its adhesion to glass fiber. In terms of saturated polyester, the polyester made of 1,6- hexanediol and 4,4- dicarboxyl-diphenyl sulfonic acid has high tensile strength and high elasticity. Excellent solvent resistance and swelling resistance, especially suitable for photographic film base. The polyester of 1,6- hexanediol and terephthalic acid is suitable for the treatment of polyester fiber.
③ Synthetic resin additive: Compared with low molecular weight plasticizer, the plasticizer using 1,6- hexanediol has excellent performance in volatility resistance, oil spray and frost resistance, migration resistance and low temperature resistance, and can be widely used in plastics, rubber, epoxy resin and other materials.
