Sourcing Phthalic Anhydride (PAN)? ChemicalDekho connects you with primary producers like IG Petrochemicals (IGPL) and Thirumalai Chemicals. Access high-purity monomers for DOP and paint resins.
Phthalic Anhydride (CAS 85-44-9) is a fundamental building block for the petrochemical industry. Its largest application is the production of phthalate plasticizers (like DOP, DBP) which make PVC flexible. It is also the essential ingredient for Alkyd Resins used in architectural paints and Unsaturated Polyester Resins (UPR) for fiberglass. Listings feature high-crystallization material in flakes and heated molten bulk tankers.
The platform ensures supply of high-grade PAN with low color and impurity levels, critical for producing clear, high-quality plasticizers and coatings.

Causes serious eye damage and skin irritation. May cause an allergic skin reaction. Harmful if swallowed. Molten product causes severe thermal burns.
Molten PAN is supplied hot in heated tankers for immediate use in large plants, saving on re-melting costs. Flakes are solid at room temp, easier for smaller users and long-distance export.
It is a direct indicator of purity. A high crystallization point (130.8°C+) ensures minimal impurities, which is vital for the color and performance of final resins.
Yes, it reacts slowly with moisture in the air to form Phthalic Acid. This can cause 'clumping' in bags and acidity issues in production.
Both are anhydrides used in resins. PAN is larger and provides better durability and gloss in alkyd paints. Maleic is smaller and provides more reactive sites for UPR curing.
