Portfolio

Four Products. One Integrated Value Chain.

IGPL's product portfolio is structured around a single, tightly coupled process: ortho-xylene in, phthalic anhydride out — with by-products recovered and downstream chemistry added. Every product in our portfolio traces back to the same reactor system at Taloja.

Integrated Chemistry

One site. One supply chain. Consistent quality since 1992.

Five PA plants, four Maleic Anhydride recovery units, and on-site DEP esterification — all at Taloja. No multi-site logistics complexity.

Our Process

One Site. Four Products. Integrated.

IGPL's product portfolio originates from a single oxidation process at its Taloja campus. This integration means consistent quality, efficient by-product recovery, and a supply chain that is compact and controllable. The same site that produces 275,110 MTPA of PA also recovers MA and BA, and adds DEP downstream.
