Description

Diisodecyl 2,2'-[(Dibutylstannylene)Bis(Thio)]Diacetate is a specialized organotin compound that functions as a highly effective heat stabilizer and lubricant in polymer processing. This product is engineered to prevent thermal degradation and enhance the flow properties of sensitive polymers during high-temperature manufacturing. It is a critical additive for industries requiring precise control over polymer stability and processing efficiency, particularly in the production of PVC and other halogenated polymers.

Application

• Primary Heat Stabilizer for PVC: Used in rigid and flexible PVC formulations, including pipes, profiles, and cables, to prevent dehydrochlorination and discoloration during processing and end-use.
• Lubricant and Processing Aid: Improves melt flow and reduces friction in polymer processing equipment, leading to higher output rates and reduced energy consumption.
• Stabilizer for Other Halogenated Polymers: Provides thermal stability in the compounding and extrusion of chlorinated polyethylene (CPE) and other halogen-containing resins.
• Additive for Specialty Adhesives and Sealants: Imparts stability and workability to formulations that are processed or cured at elevated temperatures.
• Component in Stabilizer/Lubricant One-Pack Systems: Used in pre-mixed additive packages for simplified and consistent compounding in PVC window profiles and siding.

Quality Control

Our production of Diisodecyl 2,2'-[(Dibutylstannylene)Bis(Thio)]Diacetate adheres to a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Every lot is analyzed against key parameters including tin content, color, and viscosity. A Certificate of Analysis (COA) detailing these results is provided with each shipment. Our quality protocols are designed to meet the demanding requirements of the global polymer industry.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a temperature between 15°C and 25°C (59°F and 77°F). This material is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize exposure to air after opening the original container. Keep away from heat, sparks, and open flame.
