Low Sulfate Content Aluminum Hypophosphite slightly soluble in water, high purity and high decomposition temperature. It completely solves the electrochemical corrosion risk that traditional aluminum hypophosphite may cause in high temperature and high humidity environments, providing reliability and long-term stability for your precision electronic components and high-voltage electrical equipment.
First, we need to know that aluminum hypophosphite, a highly effective flame retardant, requires a much lower addition amount than hydroxide-based flame retardants, generally between 10% and 25%. However, to be more specific, various factors need to be clearly explained.
The basic amount added is directly related to the target flame retardant rating. If you want to achieve UL94V-0, the amount added will be close to the upper limit, possibly exceeding 20%. In addition, the thickness of the product is also closely related to the amount of flame retardant used. Thin-walled products burn faster and are less likely to form a stable char layer, so more AP needs to be added.
If you are ready to choose aluminum hypophosphite as a flame retardant for your material, please let us know your material type: PET, PBT, PA, PP, or other plastics. Taixing is very professional in flame retardant formulation and will give you some advice, including how much to add or whether to add other synergists.
