Quick Details:

Chemical stability. The chemical stability of polyester mainly depends on the molecular chain structure. Polyester has excellent resistance to other reagents except for poor alkaline resistance.

(1) acid resistance. Polyester is very stable to acids (especially organic acids). After being immersed in 5% hydrochloric acid solution at 100℃ for 24h or 70% sulfuric acid solution at 40℃ for 72h, its strength does not lose, but it cannot resist the long-term action of concentrated nitric acid or concentrated sulfuric acid at room temperature.

(2) alkali resistance. The ester group on dacron macromolecule is easily hydrolyzed by alkali. At room temperature and concentrated alkali, high temperature and dilute alkali action can make the fiber damage, only at low temperature to dilute alkali or weak alkali is relatively stable.

(3) solvent resistance. Polyester has strong resistance to general non-polar organic solvents, even to polar organic solvents at room temperature. For example, at room temperature in acetone, chloroform, toluene, trichloroethylene, carbon tetrachloride soaked in 24h, fiber strength does not decrease. Under heating condition, polyester can be dissolved in phenol, xylenol, o-dichlorophenol, benzyl alcohol, nitrate

Benzene and phenol - carbon tetrachloride, phenol - chloroform, phenol - toluene and other mixed solvents.
