Purified Isophthalic Acid (PIA)

Purified Isophthalic Acid (PIA) is an organic compound. This is an isomer of Phthalic acid and Terephthalic acid. The product is used as an intermediate in the production of unsaturated polyester resins, followed by polyester and alkyd resins (mainly for surface coatings) and inks, reinforced plastics and packaging applications. Purified Isophthalic Acid (PIA) is also used as a comonomer in the production of Polyethylene Terephthalate (PET) bottle resins. It provides excellent hardness, corrosion and stain resistance, hydrolytic and thermal stability, and low resin levels.
