Description

Butyldodecylphthalate CAS NO 23761-34-4 is a high-molecular-weight phthalate ester plasticizer known for its excellent permanence and low volatility. This compound is critical for formulating durable, flexible polymer systems that require long-term performance under demanding conditions. It is primarily needed by manufacturers in the plastics, coatings, and specialty chemical industries seeking to enhance the flexibility and longevity of their products.

Application

• Primary plasticizer for polyvinyl chloride (PVC) and other polymers requiring low migration and high-temperature resistance.
• Key component in the formulation of specialty adhesives and sealants for enhanced flexibility and adhesion.
• Used in the production of high-performance industrial and automotive coatings to improve film formation and durability.
• Plasticizing agent for synthetic rubbers and elastomers in gaskets, hoses, and molded parts.
• Additive in cable and wire insulation compounds to maintain flexibility over a wide temperature range.
• Functional fluid or additive in specialty lubricants and hydraulic fluids.
• Used in the manufacture of printing inks and colorants to modify rheological properties.
• Intermediate in the synthesis of more complex chemical compounds and polymer additives.

Quality Control

Our Butyldodecylphthalate is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against comprehensive specifications, including identity, assay, and impurity profiles. A Certificate of Analysis (COA) documenting these results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep container tightly sealed when not in use to minimize moisture absorption and contamination.
