Ammonium polyphosphate (APP), phase II
Original: Decabromodiphenyl ether (decaBDE)
Proposed offset: Ammonium polyphosphate (APP), phase II
Use: Reformulated intumescent coating / textile flame-retardant systems using a suitable documented APP grade
Claim to investigate: APP is a phosphorus/nitrogen route assessed among decaBDE alternatives; phase-II APP can supply acid in an intumescent system.
Limits: The mechanism requires a compatible binder, carbon donor and blowing agent; it is not an equal-dose drop-in replacement for decaBDE. Water-based textile use requires an appropriate modified or encapsulated grade; do not transfer AP862 claims to generic APP or AP422. Current exact-grade regional SDS review is required. A July 2025 AP422 SDS lists H351/H361f, so historical alternative status does not establish a blanket lower-hazard conclusion. Verify wash durability, water resistance, smoke and fire performance in the finished article.
