Description

Isooctyl Isoundecyl Phthalate is a high-performance, mixed-chain phthalate ester plasticizer. This compound is engineered to provide superior low-temperature flexibility and permanence in polymer formulations, making it a critical component for durable, high-quality end products. It is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable plasticizers for demanding applications.

Application

• Primary plasticizer for polyvinyl chloride (PVC) in wire and cable insulation and jacketing.
• Key component in the formulation of flexible PVC products requiring excellent low-temperature performance, such as automotive interiors, hoses, and seals.
• Plasticizer for synthetic rubbers and elastomers to enhance flexibility and processability.
• Used in the production of adhesives, sealants, and caulks to improve elasticity and adhesion.
• Formulation additive for specialty coatings and inks to modify film properties.
• Processing aid in the manufacture of plastisols and other suspension-based polymer systems.

Quality Control

Our Isooctyl Isoundecyl Phthalate is produced under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against rigorous internal specifications for purity, color, acidity, and physical properties. 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 strong alkalis and organic solvents. Recommended storage temperature is between 15°C and 25°C (59°F and 77°F). Keep containers tightly sealed when not in use to minimize moisture absorption and contamination.
