Description

Bis(6-Methylheptyl) Phthalate is a high-molecular-weight phthalate ester plasticizer, valued for its excellent compatibility with a wide range of polymers and its ability to impart flexibility and durability to finished products. This compound is a critical component in formulations requiring enhanced low-temperature performance and resistance to extraction. It is primarily sought by manufacturers in the plastics, coatings, and specialty chemical industries for producing flexible PVC, synthetic rubbers, and adhesive systems.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) products such as cables, hoses, and films.
• Key ingredient in the formulation of synthetic rubbers and elastomers to improve processability and flexibility.
• Used as a functional additive in specialty coatings and adhesives to enhance film-forming properties and adhesion.
• Employed in the production of sealants and caulks to ensure long-term elasticity and weather resistance.
• Acts as a processing aid and viscosity modifier in various polymer compounding operations.
• Utilized in the manufacture of plastisols for rotational molding, dip coating, and screen printing applications.

Quality Control

Our Bis(6-Methylheptyl) 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 other critical parameters. Certificates of Analysis (COA) documenting these results are available for every shipment to guarantee traceability and compliance with your quality assurance protocols.

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 minimize moisture absorption and contamination.
