    摘要： The method of making polystyrene foam for foam products which includes utilizing atmospheric gases as the blowing agents or preferably mixing one or more of these gases and a blending agent which is non-volatile at the extrusion temperatures, introducing the mixture to a molten thermoplastic polystyrene resin containing nucleating agents such as sodium bicarbonate and citric acid and extruding the thermoplastic in the form of a foam. The resultant foam has substantially no residual blowing agent, is dimensionally stable at ambient temperatures and when used with a non-volatile blending agent can be made with small amounts of blowing agent permitting cooling of the melt without high loading on the extruder. The foam may be coextruded with one or more layers of thermoplastic film so that the resultant product is adapted for use for plates, cups, food containers or packaging and for labels for containers such as glass and plastic containers and for labels that are shrunk in place on a container.

    摘要： A process and apparatus is described by means of which the pollution of the surrounding atmosphere by the fumes of isocyanate, liberated during the continuous formation of isocyanate-based polymer foam bunstock, is minimized. The bunstock, after the foam rise and gelation is completed, is passed through a zone, installed on the bunstock conveyor, in which the foam is subjected to the action of a fine mist of water sprayed on to the top and sides of the foam bunstock. The application of water in this manner does not affect the properties or appearance of the foam and any excess water coating the surface of the foam evaporates during the remainder of the passage of the bunstock down the conveyor. The above procedure is particularly applicable to the production of foam bunstock which is based on the highly volatile toluene diisocyanate.
