Description

2-Ethylhexyl Benzyl Phthalate is a specialized high-molecular-weight phthalate ester plasticizer known for its excellent solvating power and low volatility. This compound is valued for its ability to impart flexibility, durability, and low-temperature performance to polymer matrices. It is primarily sought by formulators and manufacturers in the polymer, coatings, and specialty chemical industries for producing high-performance materials.

Application

• Primary plasticizer for polyvinyl chloride (PVC), polyvinyl acetate (PVAc), and other synthetic resins.
• Key component in the formulation of specialty adhesives and sealants requiring enhanced flexibility.
• Used in the production of high-quality, flexible coatings and films.
• Functional additive in caulks and elastomers to improve low-temperature properties.
• Plasticizing agent for cellulose derivatives and certain synthetic rubbers.
• Employed in specialty industrial applications where compatibility with strong alkali/organic solvent environments is required.

Quality Control

Our 2-Ethylhexyl Benzyl 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 identity confirmation, assay, color, acidity, and moisture content. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong alkalis and incompatible materials. For long-term storage, consider using under an inert atmosphere to maintain product integrity.
