Application
Used as an intermediate for polyester and coating resins. Mixed with terephthalic acid, isophthalic acid is used in the production of PET resins for drink plastic bottles and food packaging. The high performance polymer polybenzimidazole is produced from isophthalic acid. The acid is used as an important input to produce insulation materials.
