Description

Dinonyl Phthalate is a high-molecular-weight phthalate ester plasticizer known for its excellent permanence and low volatility. This compound is a critical component for formulating durable, flexible PVC and other polymer systems requiring long-term performance. It is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable plasticizers for demanding applications.

Application

• Primary plasticizer for polyvinyl chloride (PVC) in wire and cable insulation, automotive interiors, and flooring.
• Secondary plasticizer blended with other phthalates to enhance low-temperature flexibility and permanence.
• Functional fluid and additive in specialty lubricants and industrial greases.
• Processing aid and viscosity modifier in polymer and rubber compounding.
• Component in sealants, adhesives, and caulking compounds requiring plasticization.
• Used in the formulation of specialty coatings and inks to improve film flexibility.
• Plasticizer for synthetic leather and other coated fabric products.
• Intermediate in the synthesis of other complex esters and specialty chemicals.

Quality Control

Our Dinonyl Phthalate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay, color, acidity, and specific gravity, to meet industrial-grade specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee product integrity and traceability.

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.
