Main Applications

　　Dissolution and Processing of Polymer Materials

　　As a solvent for high-temperature engineering plastics such as polyimide, polysulfone, and polyphenylene sulfide, used in the preparation of films, fibers, or coatings (e.g., polyimide films for the production of insulating materials in the electronics industry).

　　Dissolving synthetic fibers (e.g., acrylic fibers) for use in the spinning process to improve fiber uniformity and mechanical properties.

　　Organic Synthesis and Pharmaceutical Intermediates

　　As a reaction solvent for catalytic reactions, condensation reactions, etc., particularly suitable for reactions requiring a polar environment but avoiding proton interference (e.g., Grignard reactions, nucleophilic substitution reactions).

　　In the pharmaceutical field, used for the synthesis and purification of drugs such as antibiotics and hormones, improving reaction efficiency and product purity.

　　Coatings and Inks Industry

　　As a solvent or co-solvent for high-end coatings (e.g., automotive paints, anti-corrosion paints) and inks, capable of dissolving resins and pigments, enhancing the leveling and adhesion of coatings, with a moderate evaporation rate that facilitates application.

　　Other Fields

　　Used in extraction and separation processes, such as extracting aromatic hydrocarbons from petroleum fractions or separating metal ions from organic phases.

　　As a textile auxiliary for fiber dyeing and finishing, improving dye solubility and dye uptake rates.
