Description

Diisotridecyl 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 superior flexibility, durability, and resistance to extraction in demanding polymer applications. It is a critical material for formulators and manufacturers in industries requiring high-performance plasticized products, particularly where long-term stability is paramount.

Application

• Primary plasticizer for high-performance Polyvinyl Chloride (PVC) and other polymers requiring low volatility and migration resistance.
• Key component in the production of high-temperature wire and cable insulation and jacketing.
• Formulation of durable automotive interiors, including dashboards, door panels, and under-hood components.
• Manufacture of coated fabrics, tarpaulins, and industrial membranes where weatherability is essential.
• Used in specialty sealants, adhesives, and caulks to enhance flexibility and longevity.
• Plasticizer for rotational molding applications and other specialized polymer processing techniques.

Quality Control

Our Diisotridecyl Phthalate is manufactured 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 other critical physical properties. A comprehensive 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 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 containers tightly sealed when not in use to minimize moisture absorption and contamination.
