Description

Diisononyl Phthalate (DINP) is a high-molecular-weight phthalate ester plasticizer, widely recognized for its excellent performance and versatility. Its primary value lies in imparting superior flexibility, durability, and processability to polyvinyl chloride (PVC) and other polymer matrices. This product is essential for manufacturers in the plastics, coatings, and adhesives industries seeking reliable and efficient plasticizer solutions. Diisononyl Phthalate CAS NO 68515-48-0 is a key component in formulating products that require long-lasting elasticity and resistance to extraction.

Application

• Primary plasticizer for flexible PVC products such as cables, wires, and flooring.
• Formulation of synthetic leather, coated fabrics, and automotive interior trim.
• Production of flexible films, sheets, and hoses for industrial and consumer applications.
• Modifier for adhesives, sealants, and caulks to enhance flexibility and adhesion.
• Component in printing inks and specialty coatings to improve film properties.
• Used in the compounding of various rubber and elastomer formulations.

Quality Control

Our Diisononyl Phthalate is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. The product is tested against rigorous internal specifications that assess key parameters such as ester content, color, acidity, and refractive index. While this is an industrial-grade product, our quality commitment ensures it meets the demanding requirements of polymer processing. A Certificate of Analysis (COA) detailing all test results is provided with each shipment.

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 such as strong acids and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Keep containers tightly sealed when not in use to minimize moisture absorption and prevent contamination.
