More Information
Summary:A highly expanded polystyrene resin foam is produced by using a chlorine-free fluorohydrocarbon containing at least one hydrogen atom as the flowing agent and a resinous mixture comprising polystyrene and a polymer containing oxygen, nitrogen or fluorine or another resinous mixture comprising polystyrene and a hydroxy acid or its derivative as the base polymer. On a produit une mousse en résine de polystyrène hautement expansée à l'aide d'un hydrocarbure fluoré sans chlore et contenant au moins un atome d'hydrogène en tant qu'agent d'écoulement et un mélange résineux comprenant du polystyrène et un polymère contenant de l'oxygène, de l'azote ou du fluor, ou un autre mélange résineux comprenant du polystyrène et un hydroxyacide ou son dérivé, en tant que polymère de base.
