Description

Diisobutyl Hexahydrophthalate is a high-purity diester plasticizer derived from hexahydrophthalic anhydride. This compound is valued for its excellent solvating power, low volatility, and compatibility with a wide range of polymers, providing enhanced flexibility and durability. It is a critical component for formulators and manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable performance additives.

Application

• Primary plasticizer for polyvinyl chloride (PVC) and other vinyl polymers.
• Solvent and coalescing agent in industrial and architectural coatings.
• Functional fluid and additive in specialty lubricants and greases.
• Intermediate in the synthesis of more complex ester-based chemicals.
• Plasticizer for adhesives, sealants, and caulking compounds.
• Additive to improve the flexibility and low-temperature performance of rubber compounds.
