RESEARCH

N-P PIN FRs for epoxy

Three N-phosphorylated iminophosphoranes, with different P oxidation states, were tested, in one case achieving UL 94 V-0.

Review of railway seat fire tests

Review of rail seat fire tests shows varying results with different test methods, materials and with material ageing.

Phenyl vs phenoxy phosphorus FRs

Both phenyl and phenoxy phosphorus PIN FRs showed improved effectiveness on cotton with more OH terminations.

Phosphorus FRs for battery electrolytes

Review summarises 150 studies of different phosphorus-based flame retardants in lithium-ion battery electrolytes: testing safety and electrical performance.

AlPi not skin sensitiser, not genotoxic

Tests of the PIN flame retardant AlPi conclude that it is not tested for human skin irritation and sensitisation using human keratinocyte cells, chemical modelling and biomarker analysis.
