Description

Antimony(3+) Stearate is a metallic soap compound where antimony is complexed with stearic acid. This product serves as a versatile and effective heat stabilizer and catalyst in various polymer formulations. It is primarily utilized by manufacturers in the plastics, rubber, and specialty chemical industries to enhance material performance and processing stability.

Application

• PVC Stabilizer: Acts as a highly effective heat stabilizer in polyvinyl chloride (PVC) formulations, preventing degradation during high-temperature processing.
• Polymer Catalyst: Functions as a catalyst or co-catalyst in polymerization reactions, particularly for polyesters and other condensation polymers.
• Flame Retardant Synergist: Used in combination with halogenated compounds to enhance flame retardant properties in plastics, textiles, and coatings.
• Lubricant & Release Agent: Serves as an internal or external lubricant and mold release agent in plastic and rubber compounding.
• Ceramic & Glass Precursor: Employed as an additive or precursor material in the production of specialty glasses and ceramic glazes.
• Textile Treatment: Used in the finishing of textiles to impart water repellency, flame resistance, or other functional properties.
