Aluminum Hypophosphite Low Sulfate Content is kind of new type phosphorus flame retardant, slightly soluble in water, high purity and high decomposition temperature, widely used in engineering plastics, wire and cable compounds.
Product Introduction:
1. Chemical properties: The chemical formula is Al(H₂PO₂)₃, with a molecular weight of 221.95. This chemical structure endows it with good thermal stability, with an initial thermal decomposition temperature of ≥ 280 ℃, which can effectively suppress combustion reactions at high temperatures.
2. Physical properties: Insoluble in water and alcohol, its aqueous solution is weakly acidic. This solubility characteristic allows it to remain stable in different application scenarios without being affected by the presence of moisture. At the same time, it has extremely low moisture absorption and can maintain a good physical state in humid environments.
3. Content and purity: The aluminum hypophosphite content is as high as 97-99% Min, with extremely high purity, ensuring the high efficiency and durability of flame retardant effect. The impurity content is strictly controlled, such as iron content ≤ 0.0003%, chloride content ≤ 0.03%, and heavy metal (calculated as Pb) ≤ 0.001%, ensuring the safety and stability of the product in high-end applications.

Application areas:
1. Electronic and electrical industry: Adding low sulfate content aluminum hypophosphite to plastic casings and internal components of electronic devices can effectively improve the flame retardancy of the material, reduce the risk of fire, and ensure the safe use of electronic devices. For example, the casings of computers, mobile phones, and other products, as well as insulation materials for various circuit boards.
2. In the field of automobile manufacturing: used as interior materials for automobiles, such as seats, instrument panels, carpets, etc., it can enhance the fire resistance of interior materials, delay the spread of fire in case of accidents, and provide passengers with more escape time. At the same time, it will not affect the aesthetics and comfort of the interior materials.
3. Building materials industry: applied to building insulation materials, decorative panels, etc., to make building materials have good flame retardant properties and meet building fire safety standards. It plays an important role in fire prevention in large shopping malls, office buildings, residential buildings, and other buildings, improving the overall safety of the building.
