Description

Bis(2-Propyloctyl) Phthalate is a high-molecular-weight phthalate plasticizer known for its excellent permanence and low volatility. This compound is valued for its ability to impart flexibility, durability, and low-temperature performance to polymer matrices, particularly PVC. It is a critical material for manufacturers in the plastics, polymer, and specialty chemical industries seeking high-performance plasticizers for demanding applications.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) compounds, including cables, flooring, and synthetic leather.
• Formulation of specialty polymer resins requiring enhanced low-temperature flexibility and resistance to extraction.
• Production of adhesives, sealants, and coatings where plasticizer permanence is critical.
• Component in industrial lubricants and functional fluids.
• Used in the manufacture of gaskets, hoses, and other molded rubber/plastic goods.
• Potential additive in printing inks and pigment dispersions.

Quality Control

Our Bis(2-Propyloctyl) Phthalate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications for industrial applications. A Certificate of Analysis (COA) detailing purity, identity, and key parameters is provided with every shipment to guarantee consistency and performance.

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 bases 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 minimize moisture absorption and contamination.
