Description

Dodecyl Phthalate CAS NO 21577-80-0 is a high-molecular-weight diester of phthalic acid, valued for its excellent plasticizing properties and chemical stability. This compound is a critical component in the formulation of flexible PVC and other polymer systems, where it imparts durability and low-temperature performance. It is primarily sought by manufacturers in the plastics, coatings, and specialty chemical industries for producing high-quality, flexible end-products.

Application

• Primary plasticizer for polyvinyl chloride (PVC) resins in wire & cable insulation, flooring, and films.
• Functional additive in synthetic rubber and elastomer formulations to enhance flexibility and processability.
• Solvent and carrier in specialty coatings, adhesives, and sealants requiring high solvency and low volatility.
• Intermediate in the synthesis of more complex ester-based chemicals and lubricant additives.
• Plasticizer for cellulose-based plastics and other polymer systems requiring compatibility with non-polar matrices.
