Description

Zinc Epoxyoctadecanoate CAS NO 26264-49-3 is a metallic soap compound primarily used as a high-performance stabilizer and lubricant. This product is valued for its ability to enhance the thermal stability and processing characteristics of polymers, particularly PVC, by scavenging degrading hydrochloric acid. It is an essential additive for manufacturers in the plastics, coatings, and rubber industries seeking to improve product longevity and performance under heat and mechanical stress.

Application

• Primary Stabilizer for PVC: Used in rigid and flexible PVC formulations, including pipes, profiles, cables, and films, to provide excellent long-term heat stability.
• Lubricant and Processing Aid: Acts as an internal/external lubricant in plastic compounding, improving flow properties and reducing sticking to metal surfaces during extrusion and calendering.
• Co-additive in Stabilizer Systems: Often used synergistically with calcium-based soaps and other organometallic compounds to create high-efficiency, cost-effective stabilization packages.
• Coatings and Inks: Functions as a drier and stabilizer in certain paint and printing ink formulations to control oxidation and skinning.
• Rubber Industry: Employed as an activator and processing aid in rubber compounding to facilitate mixing and vulcanization.
• Grease and Lubricant Thickener: Serves as a component in the formulation of specialty greases and solid lubricants.

Quality Control

Our Zinc Epoxyoctadecanoate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Production adheres to ISO 9001 standards, and the product meets typical industry specifications for heavy metal content and other critical impurities. A comprehensive Certificate of Analysis (COA) detailing assay, zinc content, acid value, and moisture is provided with each 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 material is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
