Description

Barium Epoxyoctadecanoate is a metal carboxylate salt primarily used as a highly effective heat stabilizer and lubricant in polymer formulations. This compound is critical for enhancing the thermal processing stability and longevity of finished plastic products, particularly PVC. It is an essential additive for manufacturers in the plastics, polymer compounding, and specialty chemical industries seeking to improve product performance and durability under high-temperature conditions.

Application

• Primary Heat Stabilizer for PVC: Used in rigid and flexible PVC formulations, including pipes, profiles, cables, and films, to prevent thermal degradation during processing and extend service life.
• Lubricant and Processing Aid: Acts as an internal/external lubricant in PVC and other polymer systems, improving flow properties, reducing sticking to equipment, and enhancing surface finish.
• Co-stabilizer in Complex Stabilizer Systems: Often used in combination with other metal soaps (e.g., calcium, zinc) and organic co-stabilizers to provide synergistic stabilization effects and cost-performance optimization.
• Wire and Cable Insulation: Imparts excellent electrical insulation properties and long-term thermal stability to PVC compounds used for wire and cable jacketing.
• Calendering and Extrusion Processes: Provides crucial thermal protection and lubrication for high-shear manufacturing processes like calendering of sheets and extrusion of profiles.
• Stabilizer for Other Halogenated Polymers: Can be employed as a stabilizer in other polymers susceptible to dehydrohalogenation, such as chlorinated polyethylene (CPE).

Quality Control

Our Barium Epoxyoctadecanoate is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent performance as a polymer stabilizer. Key parameters such as metal content, epoxy value, acid value, and moisture are controlled. A Certificate of Analysis (COA) documenting purity and specifications is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in original packaging or a moisture-proof container to prevent caking and degradation. Keep away from strong acids and oxidizing agents.
