Boron Phosphate (BPO4) Flame Retardant Synergist
Boron phosphate (BPO4) is a high-temperature-stable inorganic flame retardant synergist that combines the char-forming and vitrifying properties of boron with the acid-source activity of phosphate. At fire temperatures, BPO4 decomposes to form a boron-phosphorus oxide glass that acts as a viscous barrier coating over the polymer surface, suppressing fuel release and combustion. It is used in high-temperature ceramic-forming cable systems, specialty coatings, and as a co-synergist with aluminum phosphate or zinc borate in demanding fire-resistance applications.
