Isophthalic Acid

Description

What is Isophthalic Acid?

Isophthalic Acid (IPA) is an aromatic dicarboxylic acid, primarily used as a raw material in the production of resins, coatings, and plastics. It is a white crystalline solid with excellent thermal and chemical resistance, making it a valuable intermediate in the polymer and chemical industries.

As a key building block in unsaturated polyester resins, polyethylene terephthalate (PET), and coating materials, Isophthalic Acid enhances strength, durability, and resistance properties, contributing to high-performance end products. Chemex Chemicals supplies premium-grade Isophthalic Acid to meet the diverse requirements of industrial applications.
