Description

Butyl-n-Decyl Phthalate is a high-molecular-weight diester plasticizer derived from phthalic anhydride. This compound is valued for its excellent compatibility with a wide range of polymers, providing enhanced flexibility and durability to finished products. It is primarily sought after by manufacturers in the plastics, coatings, and specialty chemical industries for formulating high-performance materials that require low volatility and good permanence.

Application

• Primary Plasticizer for PVC: Imparts flexibility and processability to polyvinyl chloride (PVC) resins used in wire & cable insulation, flooring, and synthetic leather.
• Polymer Additive: Enhances the low-temperature flexibility and elongation properties of various elastomers and synthetic rubbers.
• Coating Formulations: Acts as a coalescing agent and plasticizer in specialty paints, adhesives, and sealants to improve film formation and elasticity.
• Lubricant and Functional Fluid Component: Used in the formulation of high-temperature lubricants and hydraulic fluids due to its stability.
• Printing Inks: Serves as a viscosity modifier and plasticizer to improve ink transfer and adhesion on flexible substrates.
