Gas phase FR effects of aluminium – phosphorus FRs
A research study analyses the differing gas phase fire-inhibition effects of two different aluminium – phosphorus PIN FRs (AHP aluminium hypophosphite, from Qingzhou Yichao Chemicals, and AlPi aluminium diethylphosphinate, from pinfa member Clariant) at 10% loading in PBT (polybutylene terephthalate).

Micron-sized magnesium oxide (MgO <75 µm) at 0 – 0.5 % loading, and AlPi (aluminium diethylphosphinate) at 0 – 14 % loading, were tested as synergistic PIN FRs in polyamide PA66, after extrusion and injection.
