Description

Diisodecyl Phthalate is a high-molecular-weight phthalate ester plasticizer known for its excellent permanence and low volatility. Its primary value lies in providing superior durability and flexibility to polymer compounds, particularly under demanding thermal and environmental conditions. This product is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking to enhance the performance and longevity of their formulations.

Application

• Primary plasticizer for polyvinyl chloride (PVC) in high-temperature wire and cable insulation.
• Key component in the formulation of durable and flexible PVC flooring, wall coverings, and automotive interiors.
• Plasticizer for synthetic rubbers and other polymers requiring low volatility and migration resistance.
• Used in the production of sealants, adhesives, and caulks to improve flexibility and adhesion.
• Functional fluid and additive in specialty lubricants and industrial coatings.
• Imparts low-temperature flexibility to plastisols and other PVC dispersion applications.

Quality Control

Our Diisodecyl Phthalate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against rigorous internal specifications for key parameters such as ester content, color, acidity, and specific gravity. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. 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.
