Uses:

  • PHTHALIC ANHYDRIDE is used in the manufacture of alkyd resins for paints and varnishes.
  • PHTHALIC ANHYDRIDE esters like DOP, DIOP, DNP, DIDP etc. are the most acceptable plasticizers for PVC products. Whereas they are the characterized by their low volatility, high water resistance and better electrical properties, other phthalate plasticizers like BBP, BOP, DCHP satisfy fast gelling and low temperature requirement of vinyl resin based products.
  • PHTHALIC ANHYDRIDE is used in the manufacture of unsaturated polyester resins.
  • PHTHALIC ANHYDRIDE finds applications as Dye intermediate and also in the manufacture of pigments. Whereas Anthraquinone and its derivatives are used in dyes, pigments like Phthalocyanines are used as colouring agents in laminates varnish, printing ink and plastic industries.
  • PHTHALIC ANHYDRIDE is used in the manufacture of tetrachlorophthalic anhydride which finds applications in reactive fire retardant in unsaturated polyesters.
