Description

Butyltris(Dibutyldithiocarbamato)Stannane is a specialized organotin compound that serves as a highly effective heat stabilizer and catalyst in polymer formulations. Its primary value lies in its ability to significantly enhance the thermal processing stability and long-term performance of various halogen-containing polymers, preventing degradation and discoloration. This product is essential for manufacturers in the PVC, polyurethane, and specialty elastomer industries seeking to improve product durability and processing efficiency.

Application

• Primary Heat Stabilizer for PVC: Used in rigid and flexible PVC formulations, including pipes, profiles, cables, and films, to prevent dehydrochlorination and maintain color stability during high-temperature processing.
• Catalyst for Polyurethane Systems: Acts as a potent catalyst in the production of polyurethane foams, elastomers, and coatings, promoting efficient reaction between isocyanates and polyols.
• Stabilizer for Other Halogenated Polymers: Provides thermal stabilization for chlorinated polyethylene (CPE), chlorosulfonated polyethylene (CSM), and other halogen-containing resins.
• Lubricant and Processing Aid: Functions as an internal lubricant in complex polymer blends, improving flow properties and mold release characteristics.
• Crosslinking Agent: Utilized in silicone rubber and other elastomer systems to facilitate crosslinking reactions under specific curing conditions.

Quality Control

Our production of Butyltris(Dibutyldithiocarbamato)Stannane adheres to a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is analyzed for critical parameters including tin content, purity, and thermal stability performance. Certificates of Analysis (COA) documenting these results are provided with every shipment. We support compliance with relevant global regulatory frameworks for polymer additives.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat, sparks, open flames, and strong oxidizing agents. Due to its light-sensitive nature, the container should be opaque or stored in darkness.
