    Abstract: Disclosed is a bead material composed of expandable polystyrene (EPS), coated with (A) one or more insecticides, preferably selected from the group consisting of fipronil, hydramethylnon and chlorfenapyr;(B) one or more glycerol esters,(C) optionally one or more polymeric binders selected from acrylate resins, aqueous polymer dispersions, or waxes; and(D) optionally further additives. A process for the production of the molding by press molding is also disclosed, wherein: (I) an EPS bead material is charged to a gas-permeable mold; (II) within the closed mold, the charge of bead material is press-molded to give a molding, with volume reduction;(III) the molding is hardened by controlling its temperature to from 20 to 100 Deg. C; and (IV) the resultant molding is removed from the mold. Further disclosed is another process for the production of the molding according by foaming-to completion, wherein: (I) an EPS bead material is charged to a gastight mold;(II) within the closed mold, the charge of bead material is foamed to completion by controlling its temperature to from 60 to 120 Deg. C, whereupon the bead material fuses to give the molding; and(III) the resultant molding is removed from the mold. These beads are suitable for making moldings that are used as insulation material in the construction industry and these mouldings are also suitable for the protection of buildings against termites.
