Application
Spiroglycol (SPG, CAS 1455-42-1) is a high-purity, specialty spiroacetal diol that serves as a high-performance building block for the synthesis of advanced polymers. Its unique spiro-ring structure imparts exceptional thermal stability, rigidity, and chemical resistance. In polymer production, it is copolymerized to produce high-performance polyesters, polyurethanes, polyether polyols, and epoxy resins. It is particularly valuable for UV-curable cycloaliphatic polyesters in powder coatings, offering enhanced mechanical properties, superior weather resistance, and high transparency. Spiroglycol is also used to synthesize acrylate/methacrylate reactive monomers for UV-curable coatings, 3D printing resins, and adhesives. In food contact materials, spiroglycol is a comonomer in polyesters for FDA/EU-compliant applications requiring long-term stability under hot-fill and sterilization conditions. Research also explores its use in biomaterials and pH-responsive drug delivery systems due to its stability in acidic environments. Xinchem offers custom synthesis and contract manufacturing of high-purity spiroglycol with flexible scaling from R&D to commercial tons. Contact us for a competitive quote and reliable global supply.
