Description

Aluminum Triphosphate CAS NO 29196-72-3 is an inorganic compound widely recognized for its utility as a corrosion inhibitor and flame retardant. Its primary value lies in its ability to form stable, protective layers on metal surfaces and to act as a synergistic agent in polymer formulations. This makes it an essential material for industries focused on enhancing the durability and safety of their products, including coatings, plastics, and construction materials.

Application

• Corrosion Inhibitive Pigments: A key component in primers and anti-corrosive coatings for steel, aluminum, and other metals, providing long-term protection.
• Flame Retardant Synergist: Used in plastics, rubber, and textiles to improve fire resistance, often in combination with other retardants like magnesium hydroxide.
• Ceramic and Glass Production: Serves as a fluxing agent and stabilizer in the manufacture of specialty glasses and ceramic glazes.
• Adhesives and Sealants: Imparts improved thermal stability and adhesion properties in high-performance bonding applications.
• Water Treatment: Acts as a scale and corrosion inhibitor in industrial cooling and boiler water systems.
• Lubricant Additive: Enhances the extreme pressure (EP) and anti-wear properties of industrial greases and oils.

Quality Control

Our Aluminum Triphosphate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against key parameters including purity, particle size distribution, and specific surface area to meet industrial-grade specifications. A Certificate of Analysis (COA) detailing these results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the product must be stored in a cool, dry place at room temperature (15-25°C/59-77°F) with low humidity. Opened containers should be resealed immediately to prevent moisture absorption and caking.
