Description

Fatty Acids, C14-18 And C16-18-Unsatd., Zinc Salts is a metallic soap derived from a blend of saturated and unsaturated fatty acids. This compound serves as a versatile and effective multi-functional additive, primarily valued for its role as a heat stabilizer and lubricant in polymer processing. It is essential for manufacturers in the plastics, rubber, and coatings industries seeking to enhance product stability and processing characteristics. The material is supplied under the CAS registry number 67701-12-6.

Application

• PVC Stabilizer: Acts as a cost-effective secondary heat stabilizer and lubricant in rigid and flexible polyvinyl chloride (PVC) formulations, improving processability and initial color hold.
• Polymer Lubricant: Functions as an internal and external lubricant in various polymer systems, including engineering plastics, to reduce friction during extrusion and molding.
• Rubber Industry: Used as an activator and processing aid in rubber compounding, aiding in dispersion of fillers and improving release properties.
• Coatings & Inks: Serves as a flatting agent, suspension aid, and viscosity modifier in certain paint, varnish, and printing ink systems.
• Cosmetics & Personal Care: Employed as an opacifying agent and texture modifier in creams, lotions, and stick formulations.
• Adhesives & Sealants: Imparts thixotropic properties and improves stability in adhesive and sealant products.

Quality Control

Our production of Fatty Acids, C14-18 And C16-18-Unsatd., Zinc Salts adheres to stringent quality management protocols. Each batch undergoes rigorous testing to ensure consistency and compliance with relevant industrial specifications. Key parameters such as zinc content, moisture, and acid value are closely monitored. A Certificate of Analysis (COA) 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, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking and performance degradation. Keep away from strong acids and oxidizing agents.
