Description

Strontium(2+) Octanoate is a metal carboxylate salt of strontium and octanoic (caprylic) acid. This compound serves as a critical heat stabilizer and catalyst in various polymer and resin systems, where it effectively mitigates degradation during high-temperature processing. It is primarily utilized by manufacturers in the plastics, coatings, and specialty chemical industries seeking to enhance the thermal stability and performance characteristics of their formulations.

Application

• PVC Heat Stabilizer: Acts as a primary or co-stabilizer in flexible and rigid polyvinyl chloride (PVC) formulations to prevent thermal degradation during extrusion, calendering, and molding.
• Polyester Catalyst: Used as a polymerization catalyst in the production of saturated polyesters and alkyd resins for coatings and composites.
• Grease & Lubricant Additive: Functions as a thickener and performance additive in the formulation of high-temperature greases and specialty lubricants.
• Drier for Paints & Inks: Serves as an efficient siccative (drying agent) in oil-based coating systems, inks, and varnishes to accelerate the oxidation and polymerization of drying oils.
• Crosslinking Agent: Employed in silicone rubber and other elastomer systems to facilitate crosslinking and improve thermal properties.
• Ceramic & Glass Precursor: Used in sol-gel processes and as a precursor for introducing strontium oxide into specialty glasses, ceramics, and optical materials.

Quality Control

Our Strontium Octanoate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, metal content, and impurity profiles 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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product quality.
