Aluminum Phosphate (AlPO4) Ceramic Flame Retardant
Aluminum phosphate (AlPO4) is an inorganic, halogen-free flame retardant filler that promotes ceramicization of polymers at high fire temperatures, forming a rigid aluminum phosphate ceramic layer that provides structural integrity and thermal barrier protection. This ceramicization mechanism is particularly effective in cable compounds, where maintaining circuit integrity during fire is critical. AlPO4 is used in combination with other inorganic FR additives such as ATH, MDH, and zinc borate in halogen-free cable compounds targeting IEC 60331 fire-resistance performance.
