Description

Strontium Dipalmitate is a metal soap compound formed from strontium and palmitic acid. This specialized chemical serves as a highly effective and thermally stable lubricant, release agent, and acid scavenger in demanding polymer processing applications. It is primarily utilized by manufacturers in the plastics, rubber, and specialty coatings industries seeking to improve product performance and processing efficiency.

Application

• Polymer Processing Aid & Lubricant: Acts as an internal and external lubricant in PVC, polyolefins, and engineering plastics to reduce friction, improve flow, and prevent sticking to metal surfaces during extrusion and molding.
• Acid Scavenger/Stabilizer: Neutralizes acidic by-products generated during the thermal degradation of halogenated polymers like PVC, thereby enhancing thermal stability and preventing equipment corrosion.
• Release Agent: Provides excellent mold release properties in the production of complex plastic and rubber components, ensuring clean demolding and high surface quality.
• Grease & Thickener Component: Used in the formulation of high-temperature, water-resistant lubricating greases and as a thickening agent for various oils.
• Cosmetics & Personal Care: Functions as an opacifying agent and viscosity modifier in creams, lotions, and stick formulations.
• Surface Coatings: Imparts matting, sanding, and lubricating properties in industrial paints, powder coatings, and varnishes.
• Wire & Cable Industry: Employed as a stabilizer and lubricant in PVC insulation and jacketing compounds for wires and cables.

Quality Control

Our Strontium Dipalmitate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, composition, and performance characteristics that meet the demanding requirements of industrial applications. A Certificate of Analysis (COA) detailing key specifications such as assay, metal content, acid value, and loss on drying is provided with every shipment to guarantee traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong acids and oxidizing agents. The material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
