SiOx Machines has installed a SiOx P35 machine in the US. The machine is used for impregnation of CO2 into plastics for later production of foamed plastic articles such as bicycle helmets. CO2 impregnation means that liquid CO2 is dissolved within plastic pellets. The CO2-loaded pellets can be stored for hours before they are transferred to a high temperature mould, for fabrication of the final foamed article. The foaming process can be used for a range of plastics including PLA (poly lactic acid), silicone, special thermoplastics, e.g. atactic polypropylene and others including thermoplastic elastomers (TPE).
