Abstract

The invention relates to a method for the production of flameproof, expandable styrol polymers (EPS) by extruding a styrol polymer melt containing a propellant and flameproof agents through a nozzle plate with subsequent under water granulation. The residence time of the flameproof agent is less than 30 minutes at a melting temperature in the region of between 140 to 220 °C.
