Description

Dicyclohexyl Phthalate (CAS NO 84-61-7) is a high-molecular-weight diester of phthalic acid, valued for its excellent plasticizing properties and low volatility. This compound is a critical component for enhancing the flexibility, durability, and workability of various polymer systems. It is primarily sought after by manufacturers in the plastics, coatings, and specialty chemical industries for formulating high-performance materials.

Application

• Primary Plasticizer for PVC and other Polymers: Imparts superior flexibility and elongation to polyvinyl chloride (PVC) resins used in cables, films, and synthetic leather.
• Specialty Adhesives and Sealants: Acts as a processing aid and flexibilizer to improve the tack and low-temperature performance of adhesive formulations.
• Coatings and Inks: Serves as a coalescing agent and plasticizer in solvent-based coatings, lacquers, and printing inks to enhance film formation and elasticity.
• Rubber Compounding: Used as a secondary plasticizer and softener in various synthetic and natural rubber compounds.
• Lubricant Additive: Functions as an extreme pressure (EP) additive and viscosity modifier in specialty lubricating greases and fluids.
• Chemical Intermediate: Employed in the synthesis of more complex esters and specialty chemicals for niche industrial applications.
