Description

Barium Cadmium Tetrastearate is a specialized metallic soap compound, functioning as a highly effective heat stabilizer and lubricant in polymer formulations. Its primary commercial value lies in its synergistic ability to prevent thermal degradation and enhance processing characteristics in halogen-containing plastics. This product is essential for manufacturers in the plastics and polymer industries, particularly those producing PVC and other vinyl-based materials requiring long-term thermal stability during extrusion and molding processes.

Application

• Primary heat stabilizer for flexible and semi-rigid Polyvinyl Chloride (PVC) compounds.
• Synergistic component in mixed-metal stabilizer systems for enhanced performance.
• Processing aid and lubricant in PVC calendering, extrusion, and injection molding.
• Stabilizer for PVC applications including wire and cable insulation, films, sheets, and profiles.
• Improves initial color hold and long-term stability of finished PVC products.
• Used in the formulation of certain paints, coatings, and sealants requiring metal soap additives.

Quality Control

Our Barium Cadmium Tetrastearate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, metal content, and performance characteristics as a polymer stabilizer. While this is an industrial-grade product, we adhere to strict internal specifications for purity and heavy metal limits. A Certificate of Analysis (COA) detailing assay, moisture content, and other relevant parameters is provided with every shipment.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after initial opening to minimize exposure to atmospheric humidity. Keep away from strong acids and oxidizing agents.
