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...

Polyurethane insulation foam (PUF) was surface treated with silica (SiO2), by acid and alkali hydrolysis, then lyophilised to generate a silica aerogel at 13 – 33% w/w loading on the foam. The nano-porous structure of the aerogel resulted in improved thermal...
