1. Halogen-Free Flame Retardant For PBT & PET: Aluminum hypophosphite (AHP, CAS 7784-22-7) is a phosphorus-based halogen-free flame retardant widely used in glass-fiber-reinforced PBT and PET compounds, helping achieve UL94 V-0 ratings for connectors, relays and electronic components.
2. For Polyamide (PA) Compounds: AHP provides effective flame retardancy in PA6 and PA66 formulations, supporting halogen-free grades for electrical enclosures, automotive parts and industrial components requiring good tracking resistance.
3. For PU, TPU & Epoxy Systems: Aluminum hypophosphite works in polyurethane, TPU and epoxy formulations, reducing flame spread and smoke generation in adhesives, coatings, foams and elastomeric parts.
4. High Thermal Stability For Processing: With a high decomposition temperature and low water solubility, AHP withstands high-temperature molding and extrusion processes, maintaining flame-retardant performance in engineering thermoplastics without affecting melt flow significantly.
5. Low Smoke & Good Electrical Properties: AHP-based systems deliver low smoke density, low corrosivity and stable electrical insulation, supporting flame-retardant requirements in electrical, electronic and connector applications.
6. Consistent Quality For Global Industry: Supplied as high-purity white crystalline powder with fine particle size, consistent quality and flexible packaging, AHP gives engineering-plastic and electronic-material manufacturers a dependable halogen-free flame-retardant additive with stable supply.
