Description

Isoundecyl Undecyl Phthalate is a high-molecular-weight phthalate ester plasticizer. This compound is valued for its excellent permanence and low volatility, providing durable performance in demanding polymer applications. It is primarily sought by manufacturers in the plastics and specialty polymer industries for formulating flexible PVC and other elastomeric products that require long-term stability.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) compounds, including wire and cable insulation, flooring, and automotive interiors.
• Specialty additive in synthetic rubber and elastomer formulations to enhance flexibility and processability.
• Component in sealants, adhesives, and coatings where low migration and good compatibility are required.
• Used in the production of plastic films and sheets that demand high-temperature resistance and durability.
• Plasticizer for polymer gels and specialty materials in industrial applications.
