聚磷酸銨APP Ammonium Polyphosphate
CAS: 68333-79-9
粒徑: D50約15um
磷含量: 31~32%
氮含量: 14~15%
分子式(Molecular Formula):（NH4PO3）n
分子結構式(Structural Formula):
應用（Application) ：
主要用於膨脹型防火塗料和熱固性樹脂中（如聚胺酯硬泡、UP樹脂、環氧樹脂等），也
可用於纖維、木材和橡塑製品的阻燃。由於該APP具有高分子量（n>1000）和高穩定性,
故也可作為膨脹型阻燃熱塑性塑膠的主要有效成分，特別適用於製造電子部件的達到UL 94-
V0的PP中。
It can be used in expanding fireproof material, such as polyurethane, UP resin and
epoxy resin. It can also be used in the retardant of fiber, wood and plastic materials.
Due to its high molecular weight(n>1000) and good heat stability, APP can be used as
main ingredient of expanding retardant thermoplastic. Especially used in the PP
achieving UL94-V0 for electronic unit.
