Description

6-Methyloctyl Nonyl Phthalate is a specialized high-molecular-weight phthalate plasticizer. This compound is valued for its excellent compatibility with a wide range of polymers, providing enhanced flexibility and durability to finished products. It is primarily utilized in the formulation of high-performance plastic compounds where superior low-temperature properties and resistance to extraction are required.

Application

• Primary plasticizer for PVC (polyvinyl chloride) resins in wire and cable insulation.
• Key component in the production of flexible films and sheets for industrial and construction applications.
• Formulation of sealants and adhesives requiring long-term flexibility and weatherability.
• Plasticizer for synthetic leather and coated fabrics.
• Additive in specialty polymer blends and elastomers to improve processability and end-use performance.
• Used in the compounding of automotive interior parts and other molded plastic goods.

Quality Control

Our 6-Methyloctyl Nonyl Phthalate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, acidity, and ester content. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance protocols.

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 prevent moisture absorption.
