ATH effective as FR and smoke suppressant in epoxy
Aluminium tri-hydroxide (ATH) powder was tested at 0 – 15% loading in epoxy resin (E51) in 4 mm sheets. Peak heat release rate was reduced by nearly 30% by 15% ATH compared to neat epoxy, total smoke release was reduced by nearly 18% and carbon monoxide production rate reduced by over 30%.

READ MOREHyphosphite PIN FRs for cotton
A research paper tests calcium hypophosphite (CaPi) and magnesium hypophosphite (MgPi) as PIN FRs for cotton fabrics, also with nano-particles of a clay and a silsesquioxane as synergists (sodium montmorillonite, octa-ammonium polyhedral oligomeric silsesquioxane POSS). CaPi showed slightly better flame retardant effectiveness (LOI 23 at 15% weight loading CaPi on cotton, compared to 21 with 14% MgPi and 18 for untreated cotton fabric).
READ MOREResearchers propose “Flame Retardancy Index”
Several leading materials fire scientists have proposed a dimensionless "Flame Retardance Index” for flame retarded (compounds), based on cone calorimetry data: pHRR (peak heat release rate), THR (total heat release) and TTI (time to ignition). Each of these reflects a different aspect of fire performance.
