Description

2-Ethylhexyl Nonyl Phthalate is a specialized high-molecular-weight phthalate plasticizer known for its excellent performance characteristics. This compound is valued for its ability to impart superior flexibility, durability, and low-temperature properties to polymer matrices. It is primarily sought after by manufacturers in the plastics, coatings, and specialty chemical industries for formulating high-performance products requiring enhanced processing stability and longevity.

Application

• Primary plasticizer for polyvinyl chloride (PVC) resins in wire and cable insulation, flooring, and automotive interiors.
• Key component in the formulation of synthetic rubbers and elastomers to improve flexibility and resilience.
• Used as a processing aid and secondary plasticizer in specialty adhesives and sealants.
• Employed in the production of flexible films and sheets for packaging and industrial applications.
• Functional additive in coatings and inks to enhance film-forming properties and adhesion.
• Plasticizing agent for cellulose-based and other specialty polymers.

Quality Control

Our 2-Ethylhexyl Nonyl Phthalate is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot is analyzed against stringent internal specifications, which typically include assessment of appearance, specific gravity, refractive index, acid value, and ester content. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

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 prevent moisture absorption and contamination.
