丙二醇系列
Isophthalic Acid (IPA, CAS 121-91-5) is a high-purity, white crystalline powder or granulate. It is insoluble in cold water, slightly soluble in hot water, and easily soluble in ethanol, acetone, and glacial acetic acid. As a critical dicarboxylic acid derivative, IPA serves as a premier chemical building block for fabricating advanced polymers and specialty chemicals. Compared with Paraxylene-derived PTA, the unique meta-structured aromatic ring of IPA imparts downstream resins with exceptional elasticity, superior optical clarity, strong impact resistance, and elite chemical anti-corrosion properties. It is highly specified in processing premium unsaturated polyester resins (UPR), advanced alkyd coatings, saturated polyester powder coatings, PET fiber modifications (such as low-melting co-polyesters), and specialty polyamide adhesives.

Core Applications
Advanced Industrial Coatings & Alkyd Lacquers: Deployed to synthesize saturated polyester powder coatings and waterborne industrial finishes. It delivers superb anti-yellowing attributes, weatherability, and elite salt-spray resistance while reinforcing paint film hardness and substrate adhesion.
High-Performance Unsaturated Polyester Resins (UPR): Acts as a fundamental co-reactant in specialized UPR lines to yield heavy-duty Fiberglass Reinforced Plastics (FRP), chemical storage tanks, industrial piping, and marine gel coats requiring extreme water and chemical resistance.
Polyester (PET) & Fiber Modification: Integrated as a key modifying co-monomer in PET resin packaging, engineered films, and Low Melting Fibers (LMF). It disrupts polymer crystallinity, lowers melt processing temperature, and elevates bottle clarity and impact toughness.
Specialty Adhesives & Functional Inks: Applied in fabricating technical polyester hot-melt adhesives, flexographic printing inks, and as a durable polymer chain extender in engineered polyamides.
Packaging & Storage
Packing: Available in standard industrial 1100 KGS or 1000 KGS jumbo bags (PP woven bags with moisture-proof PE liners). Small-scale trial lots support 25 KGS multi-layer kraft paper bags.
Storage: Store in a perfectly dry, cool, and well-ventilated chemical warehouse away from extreme heat or direct ignition. Strictly isolate from powerful oxidizers and strong alkaline compounds. Protect from humidity, rain, and package puncture during maritime transit.
