Description

Heptylnonylphthalate CAS NO 19295-81-9 is a high-molecular-weight phthalate ester plasticizer, specifically a mixed alkyl chain derivative. This compound is valued for its excellent compatibility with a wide range of polymers, providing enhanced flexibility, durability, and low-temperature performance to the final product. It is primarily needed by manufacturers in the plastics, polymer, and specialty chemical industries for producing flexible PVC, synthetic rubbers, and other elastomeric materials.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) products such as cables, hoses, and films.
• Performance additive in synthetic rubber formulations to improve elasticity and processability.
• Component in specialty adhesives and sealants to adjust viscosity and flexibility.
• Processing aid in the manufacture of plastisols and organosols for coatings and molded goods.
• Functional fluid additive in industrial lubricants and greases.
• Intermediate in the synthesis of other specialty esters and chemical derivatives.

Quality Control

Our Heptylnonylphthalate is produced under a rigorous quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, acidity, and other critical parameters. Certificates of Analysis (COA) are provided and the product can be manufactured to align with relevant industry standards upon request.

Storage

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