Description

Barium Bis[3-(Octadecylthio)Propionate] is a high-performance organometallic compound, specifically a barium carboxylate salt of a long-chain thioether acid. This product is a critical heat stabilizer and lubricant for polymer processing, where it effectively prevents thermal degradation during high-temperature operations. It is primarily needed by manufacturers in the plastics and polymer industries seeking to enhance the durability and processability of their materials.

Application

• Primary heat stabilizer for polyvinyl chloride (PVC) and other halogenated polymers.
• Acts as a synergistic co-stabilizer in mixed-metal stabilizer systems for enhanced performance.
• Provides lubricating properties in rigid and flexible PVC formulations, improving flow and mold release.
• Used in the production of calendered films, sheets, and profiles requiring high clarity and thermal stability.
• Application in wire and cable insulation compounds for long-term thermal aging resistance.
• Stabilizer component for specific engineering plastics processed at elevated temperatures.
