    摘要： A mixing method and apparatus for preparing multi-component plastic materials, especially polyurethanes, which are mixed before being fed into a mould.
    According to the invention, a first and at least a second main component (A, B) are mixed by feeding them into a limited area (2a) of a mixing chamber (2), through lateral inlet apertures (3, 4) symmetrically arranged with respect to a plane comprising the longitudinal axis of the chamber (2), and in which a third or secondary component (C) to be mixed is fed in through a channel (9a) opening in the chamber upstream of said inlet apertures (3, 4) and orientated so as to direct the flow of the third component (C) towards said mixing area (2a) in the direction of flow of the mixture.

    摘要： A plastic sheet capable of being shaped by a cold room temperature tool, said sheet being a semi-rigid thermoformable plastic foam doped with carbon black having a concentration within a range of 0.0000081 to 0.0081% by weight of the foam. And a method of forming a product from such sheet by heating it to its thermoforming temperature range by infrared (IR) heat and placing and compressing the sheet between mold parts of a cold tool, the IR heat preferably being generated by quartz lamp electric heaters.
