Aluminium Hypophosphite

Aluminium Hypophosphite (Al (H2 PO2 )3 is kind of new type phosphorus flame retardant, slightly soluble in water, high purity and high decomposition temperature,(Al (H2 PO2 )3 is widely used in engineering plastics, wire and cable compounds.Shandong taixing produce two type : Aluminium Hypophosphite ( Low Sulfate Content,aht-220B ) and regular Aluminium Hypophosphite ( HT-220A) two type (Al (H2 PO2 )3.

Physical and Chemical Properties

Key Advantage

High TGA: TGA(1%) ≥310℃

High Stable Quality:Purity mainly stable in 96.0%-97.5%

Application areas:

1. Plastic industry: widely used in elastomers and soft rubber such as PP, PE, TPE, TPR, as well as modified engineering plastics such as PA6, PET, PBT. Adding aluminum hypophosphite to PET can significantly reduce the heat release rate and combustion heat generation, increase the amount of char formed after combustion, and achieve UL94 standard V-0 flame retardant performance. Compared with traditional PET flame retardants, the flame retardant effect can be improved by 60%.

2. In the field of coatings: Adding it to coatings can effectively improve their fire resistance and achieve a first level fire rating. When a fire occurs, coatings containing aluminum hypophosphite quickly form a fire-resistant insulation layer, preventing the spread of flames and buying valuable time for personnel evacuation and firefighting. They are commonly used in fire-resistant coatings for buildings, ships, vehicles, etc.

3. Rubber and resin: Used as flame retardants in the production of materials such as rubber, epoxy resin, unsaturated resin, acrylic resin, and polyurethane. Adding aluminum hypophosphite to rubber products can improve their flame retardancy, and is used for rubber products such as wire and cable sheaths, conveyor belts, etc. that require flame retardancy; Aluminum hypophosphite can enhance the flame retardant ability of resin materials and is widely used in fields such as electronic and electrical casings, building decoration materials, etc.

Production advantages:

Advanced production technology: Adopting a mixed hydrolysis process of high-purity aluminum sulfate and sodium hypophosphite solution, strictly controlling reaction conditions, ensuring excess aluminum sulfate, and ensuring product purity and quality stability. During the production process, precise control of reaction temperature, time, material ratio, and other parameters is used to ensure uniform and stable product performance, meeting the strict requirements of different customers for product quality.

Packaging :Net weight 25kg/bag, Compound paper-plastic bag and inner aluminum foil

Storage and Attention: Keep in dry, room temperature and moisture proof condition, preventing the heating.
