Nano foam fights fire

Researchers at Strathclyde University in Glasgow, Scotland, have developed a fire-retardant foam rubber based on clay that could save countless lives. The modified polyurethane contains nanoscale particles of clay that prevent the material from disintegrating during a blaze and prevent the fire from spreading. The composite sidesteps the need for high levels of toxic and environmentally harmful bromates and organophosphates explain the developers John Liggat and Richard Pethrick. The invention comes at a time when stringent EU regulations are demanding action to reduce use of the current chemicals to a minimum.
