Description

Butyl Octyl Phthalate is a high-performance, high-molecular-weight phthalate ester plasticizer. This compound is valued for its excellent compatibility with a wide range of polymers, providing superior low-temperature flexibility and durability to the final product. It is primarily used by manufacturers in the plastics, coatings, and specialty chemical industries seeking to enhance the performance characteristics of polyvinyl chloride (PVC) and other resin systems.

Application

• Primary Plasticizer for PVC: Imparts excellent flexibility, low-temperature performance, and durability to PVC products like wire and cable insulation, automotive interiors, and synthetic leather.
• Co-Additive in Polymer Blends: Used alongside other plasticizers to fine-tune processing characteristics and final properties in various polymer formulations.
• Adhesive and Sealant Formulations: Acts as a processing aid and flexibilizer in solvent-based and plastisol adhesive systems.
• Industrial and Protective Coatings: Enhances the film-forming properties, flexibility, and adhesion of coatings for fabrics, metals, and other substrates.
• Specialty Chemical Intermediate: Serves as a raw material in the synthesis of more complex esters and functional chemicals.

Quality Control

Our Butyl Octyl Phthalate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, acidity, and other critical parameters. A Certificate of Analysis (COA) detailing these results is provided with each shipment to guarantee consistency and compliance with your formulation requirements.

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 alkalis 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.
