Description

Diisononyl Cyclohexane-1,2-Dicarboxylate is a high-performance, non-phthalate plasticizer derived from cyclohexane dicarboxylic acid. This compound matters for its excellent compatibility with a wide range of polymers, offering superior low-temperature flexibility and thermal stability. It is primarily needed by manufacturers in the plastics, polymer, and specialty chemical industries seeking safer, more durable alternatives for sensitive applications.

Application

• Primary plasticizer for PVC, especially in sensitive applications like medical tubing and food contact films.
• Key component in high-performance sealants, adhesives, and caulks requiring low volatility and migration resistance.
• Functional additive in synthetic rubber and elastomer formulations to enhance flexibility and durability.
• Plasticizer for wire and cable insulation where long-term thermal and electrical stability is critical.
• Modifier in specialty polymer blends and coatings to improve low-temperature performance and weatherability.
• Base fluid for high-performance lubricants and functional fluids in demanding industrial environments.
