Description

Di-iso-Decyl Phthalate (DIDP) is a high molecular weight phthalate ester plasticizer known for its excellent permanence and low volatility. This compound is critical for formulating durable, flexible PVC products that require long-term performance under demanding conditions. It is primarily needed by manufacturers in the wire and cable, automotive, and construction industries seeking reliable plasticizers for extended service life.

Application

• Primary Plasticizer for PVC: Used in the production of flexible polyvinyl chloride (PVC) compounds for its compatibility and processing characteristics.
• Wire and Cable Insulation: Imparts excellent electrical properties and long-term flexibility to insulation and jacketing materials.
• Automotive Interior Components: Employed in the manufacture of dashboard skins, door panels, and other interior trim requiring low fogging and migration resistance.
• Flooring and Wall Coverings: Provides durability and flexibility to vinyl flooring, wallcoverings, and synthetic leather.
• Coated Fabrics and Tarpaulins: Used in plastisols for coating textiles to create waterproof, flexible materials.
• Sealants and Adhesives: Acts as a plasticizer in various sealant and adhesive formulations to improve workability and final properties.
• Polymer Modification: Serves as a processing aid and plasticizer for other polymers beyond PVC, such as certain rubbers and synthetic resins.

Quality Control

Our Di-iso-Decyl Phthalate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing, including gas chromatography (GC) for assay and impurity profiling. A Certificate of Analysis (COA) detailing specific results for each parameter is provided with every shipment, confirming compliance with agreed specifications and industry standards.

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.
