Overview of Isophthalic Acid

Isophthalic acid is a aromatic dicarboxylic acid that is used as a raw ingredient in the resin, plastic and polymer industry. It is mostly found in coatings, polyester resins and engineering plastics. The formula for it is C8H6O4 which appears as a white solid.

If you are not a technical person isophthalic acid may be described as a strengthening chemical that increases the strength, durability, and the chemical stability of plastic as well as resins. Because it has a stable molecular structure as well as its reactivity it is a preferred ingredient for high-performance polymer systems.

Isophthalic acid is important in the plastic and rubber industry because it is used in polyester resins, specialty coatings, and many industrial plastic products.

Applications of Isophthalic Acid

Polyester Resin & Engineering Plastics

Isophthalic acid is often used to make polyester resins stronger, more stable at high temperatures, and more resistant to chemicals. These resins are found in reinforced plastics and industrial parts.

PVC & Vinyl-Based Applications

In plastic processing, isophthalic acid is added to Polyvinyl Chloride blends to make them more rigid, durable, and long-lasting.

Adhesives & Laminated Products

Isophthalic acid is used with Polyvinyl Butyral in resins and adhesives, especially where strong bonding and chemical resistance are needed.

Coatings & Emulsion Systems

If combined when combined with Polyvinyl Acetate Isophthalic acid-based resins increase the hardness of coatings, adhesion and resistance to stress in the environment.

Safety & Handling Guidelines

• Place in a cool dry, well-ventilated and dry location.

• Close containers securely even when not being used.

• Do not make contact for too long with the eyes and skin

• Be sure to avoid inhaling dust when handling

• Use protective gloves, goggles, and suitable clothing

• Follow standard industrial chemical handling procedures

• Dispose of material according to local environmental regulations
