Description

Isodecyl Isotridecyl Phthalate is a high-performance, branched-chain phthalate ester plasticizer. This compound is valued for its excellent compatibility with a wide range of polymers and its ability to impart superior low-temperature flexibility and durability to finished products. It is a critical raw material for manufacturers in the plastics, coatings, and adhesives industries seeking to enhance the performance characteristics of their formulations.

Application

• Primary plasticizer for flexible Polyvinyl Chloride (PVC) compounds, including wire & cable insulation, flooring, and synthetic leather.
• Key component in the formulation of high-performance adhesives and sealants, improving flexibility and adhesion.
• Used as a plasticizer and coalescing agent in specialty paints, coatings, and printing inks.
• Imparts low-temperature flexibility and weatherability to rubber and elastomer products.
• Employed in the production of caulks and mastics for construction applications.
• Functional additive in polymer dispersions and latex products.

Quality Control

Our Isodecyl Isotridecyl 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 physical-chemical properties. Certificates of Analysis (COA) documenting these results are provided to guarantee batch-to-batch consistency and compliance with industry standards.

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 minimize moisture absorption and contamination.
