Description

Antimony Oxide (Sb2O3), Reaction Products With Talc is a specialized inorganic compound designed to enhance material properties in demanding industrial applications. This product offers a synergistic combination of antimony oxide's flame-retardant efficacy with the physical reinforcement and cost-effectiveness of talc. It is engineered for manufacturers seeking a high-performance, multifunctional additive that improves both fire safety and mechanical characteristics in polymer composites. Key industries that utilize this material include plastics, rubber, and coatings.

Application

• As a highly effective synergistic flame retardant in polyolefins (PP, PE), PVC, and engineering plastics.
• To improve smoke suppression and char formation in fire-retardant cable compounds and wire insulation.
• As a functional filler in rubber formulations for conveyor belts, hoses, and gaskets requiring enhanced fire resistance.
• In thermoplastic composites for automotive interior parts, electrical enclosures, and construction materials.
• To provide reinforcement and dimensional stability while concurrently imparting flame retardancy.
• In specific intumescent coating systems as a component of the fire-protective layer.

Quality Control

Our production of Antimony Oxide (Sb2O3), Reaction Products With Talc adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as antimony oxide content, particle size distribution, and loss on ignition are rigorously tested. Certificates of Analysis (COA) documenting full specifications are provided with each shipment to support your quality assurance and regulatory compliance needs.

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 initial opening to prevent moisture absorption, which can affect flow properties and performance.
