    Abstract: Disclosed is a method for producing a microcellular foam polypropylene thick board, by foaming a polypropylene motherboard by a flat foaming equipment, wherein the polypropylene motherboard bears a core structure and a pore canal structure in the core of the foam polypropylene motherboard, shortening a diffusion path of supercritical carbon dioxide into a polypropylene matrix, thus reducing the saturation time required for diffusion equilibrium and significantly increasing the production efficiency. Also provided is a method for preparing the foam polypropylene motherboard bearing the pore canal structure in the core, by extrusion molding, from general polypropylene as the raw material. The method described in the present invention may be used to produce the microcellular foam board with small cell size, high cell density and high thickness.

    Abstract: Foamed polypropylene-resin particles are obtained by dispersing polypropylene-resin particles containing polyethylene glycol and/or glycerin together with an aqueous dispersion medium in a pressure-resistant container; introducing carbon dioxide gas as a foaming agent into the pressure-resistant container; impregnating the polypropylene-resin particles with the foaming agent under a heating and pressure condition; and then discharging the polypropylene-resin particles into an area having a lower pressure than an internal pressure of the pressure-resistant container and having an atmosphere temperature of higher than 80° C. and not higher than 110° C. The foamed polypropylene-resin particles can yield an in-mold foam molded body at a low heated water vapor pressure for molding, do not lose moldability at a high heated water vapor pressure for molding, have a wide heated water vapor range for molding, exhibit good moldability even when a mold with a complicated shape, a large mold, or a similar mold is used.

    Abstract: A method for infusing gas into a thermoplastic material includes positioning a sheet of a thermoplastic material into a vertical or substantially vertical position; positioning a sheet of a gas-permeable material into a vertical or substantially vertical position; and winding together the positioned sheet of thermoplastic material sheet and the positioned sheet of gas-permeable material to form a roll of the thermoplastic material interleaved with the gas-permeable material, the interleaved roll having a longitudinal axis oriented in a vertical or substantially vertical position. The method also includes exposing the interleaved roll to an atmosphere of a gas pressurized to infuse the thermoplastic material with the gas, while the longitudinal axis of the interleaved roll is oriented in a vertical or substantially vertical position; and then unwinding the gas-infused interleaved roll, while the longitudinal axis of the interleaved roll remains in a vertical or substantially vertical position.

    Abstract: A first polymer (preferably in granular form) is exposed to a gas at a pressure higher than atmospheric pressure to introduce the gas into the polymer. This occurs at a temperature from the glass transition temperature to the melting temperature when the first polymer is crystalline or semi-crystalline in nature, or at a temperature below the glass transition temperature when the first polymer is amorphous in nature. Optionally, the gas-laden polymer may then be mixed with a second polymer. The polymer is then melted to produce a foamed article.
