High-purity isophthalic acid with low levels of colored impurities and metal contaminants.
Consistent crystalline structure ensuring excellent solubility and reactivity in polyester synthesis.
Superior thermal stability compared to terephthalic acid, enabling broader processing windows in resin production.
Optimized particle size distribution for improved handling, dispersion, and blending efficiency in solid-state polymerization.
Compliant with global regulatory requirements for industrial chemical use, including REACH and TSCA.
Unsaturated polyester resins (UPRs) for marine, automotive, and construction composites.
Curable coatings and high-performance gel coats requiring enhanced weather resistance and gloss retention.
Specialty polyesters for flexible packaging films with improved clarity and barrier properties.
Ion-exchange resins and functionalized polymers where aromatic ring substitution position enables tailored crosslinking density.
