    Abstract: Embodiments disclose a foamed, flame-proofed molded body, comprising at least one thermoplastic polymer including a zeolite material in an amount from 0.1 percent by mass to 5.0 percent by mass, based on the weight of the foamed polymer, wherein the thermoplastic polymer is selected from the group consisting of acrylonitrile butadiene styrene (ABS), styrene acrylonitrile (SAN), polystyrene (PS), polycarbonate (PC), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyamide (PA) or mixtures thereof. The foamed polymer further includes hydrous foam cells, and the zeolitic material is at least partially present in dehydrated form. Embodiments disclose a molding compound underlying the molded body, a method for foaming a thermoplastic polymer, and the use of the foamed molded body.

    Abstract: Polyurethane composites and methods of preparation are described herein. The methods of making the polyurethane composite can include mixing (1) at least one isocyanate selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (2) at least one polyol, (3) an inorganic filler, and (4) an evaporative coolant in an extruder to form a mixture. The method also include extruding the mixture into a mold cavity, generating heat in the mold cavity from the reaction of the at least one isocyanate and the at least one polyol, and allowing the evaporative coolant to migrate to an interface between the mixture and the interior mold surface. The temperature of the mixture causes evaporation of the evaporative coolant at the interface thereby removing heat at the interface. Suitable evaporative coolants for use in the methods of making the polyurethane composites include hydrofluorocarbons and hydrochlorofluorocarbons.
