Description

Diheptylundecyl Adipate is a high-molecular-weight diester plasticizer derived from adipic acid. This compound is valued for its excellent compatibility with a wide range of polymers, providing enhanced flexibility and low-temperature performance. It is primarily utilized by manufacturers in the plastics, rubber, and specialty lubricant industries seeking a durable and efficient plasticizing agent.

Application

• Primary plasticizer for PVC (polyvinyl chloride) and other vinyl polymers, imparting flexibility and durability.
• Key component in the formulation of synthetic lubricants and functional fluids requiring high thermal stability.
• Processing aid and secondary plasticizer in elastomers and rubber compounds to improve low-temperature properties.
• Used in the production of sealants, adhesives, and caulks to enhance workability and final product performance.
• Functional additive in paints, coatings, and inks to modify rheological properties and film flexibility.
• Plasticizer for specialty wire and cable insulation formulations demanding good electrical properties.
