Description

Zinc Caprylate is a versatile organometallic compound, specifically the zinc salt of caprylic acid, valued for its role as a stabilizer and catalyst in polymer systems. Its primary commercial value lies in its effectiveness as a heat stabilizer for polyvinyl chloride (PVC), where it helps prevent degradation during processing and extends the material's service life. This product is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking reliable additives for material enhancement.

Application

• PVC Heat Stabilizer: A key component in flexible and rigid PVC formulations to prevent thermal degradation during extrusion, calendaring, and molding processes.
• Polymer Additive: Functions as a lubricant and processing aid in various polymer systems to improve flow properties and surface finish.
• Catalyst Precursor: Used in organic synthesis and the production of specialty chemicals as a catalyst or catalyst component.
• Fungistatic Agent: Employed in certain coatings, sealants, and materials where mold and mildew resistance is required.
• Cosmetic Ingredient: Acts as a opacifying agent and viscosity modifier in personal care formulations.
• Wood Preservative: Incorporated into treatments to protect wood from fungal decay.

Quality Control

Our Zinc Caprylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analysis to ensure it meets precise specifications for metal content, purity, and physical properties. Certificates of Analysis (COA) documenting key parameters such as assay, moisture content, and heavy metal limits are available upon request to support your quality assurance protocols.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
