    摘要： This invention provides a method for stably adding a predetermined amount of supercritical carbon dioxide at a fixed delivery rate into a forming machine and also a process for producing an expanded thermoplastic resin product by making use of the addition method. Carbon dioxide is charged from a liquefied carbon dioxide cylinder (1) into a predetermined amount deliverable pump (2) while allowing the carbon dioxide to remain in a liquefied state. When the carbon dioxide is pressurized and delivered by the predetermined amount deliverable pump (2), a delivery pressure of the carbon dioxide is controlled at an optional pressure within a range of from a critical pressure (7.4 MPa) of carbon dioxide to 40 MPa to deliver the carbon dioxide without any fluctuation of the amount of the delivery by setting up the pressure of a pressure control valve (3). The carbon dioxide is heated to a critical temperature (31° C.) of carbon dioxide or higher to convert it into supercritical carbon dioxide. This supercritical carbon dioxide is then added to a molten thermoplastic resin in the forming machine (4).

    摘要： Disclosed is a process for the production of an injection-expansion molded, thermoplastic resin product. The process comprises a gas dissolving step, a cooling step, a metering and injection step, and an expansion controlling step. Specifically, a thermoplastic resin is molten in a continuous plasticator (1), supercritical carbon dioxide and/or nitrogen is added as a blowing agent, and the blowing agent and the thermoplastic resin are formed into a mutually-dissolved state. The resultant molten resin composition is cooled within the plasticator while maintaining a pressure equal to or higher than a critical pressure of the blowing agent. The thus-cooled molten resin composition is metered by an injector (7) and is filled in a mold (8). An internal pressure of the mold is lowered beyond the critical pressure of the blowing agent to produce cell nuclei, whereby the cell diameter is controlled. The blowing agent is maintained in a supercritical state up to the metering and injection step.

    摘要： The expanded product of the present invention is an expanded product having a density of from 0.02 to 0.7 g/cm3, which is obtained by expanding ultra-high-molecular-weight polyethylene having a viscosity average molecular weight of from 300,000 to 10,000,000. This expanded product can be prepared by adding carbon dioxide to ultra-high-molecular-weight polyethylene in the molten state in an extruder, and expanding the resin by extrusion such that each of the surface temperature and the central part temperature of the resin immediately after discharge from the die may be a predetermined temperature, while at the same time setting the residence time and pressure of the resin at the die section to specific values. Based on these, the invention provides an expanded product with good external appearance, having a skin layer to which the functions such as light weight, insulating property, sound absorption, low dielectric constant, impact absorption, flexibility and the like can be imparted without significantly deteriorating the excellent features of abrasion resistance, self-lubrication, impact strength, cryogenic properties and chemical resistance that are inherent to ultra-high-molecular-weight polyethylene; and a process for preparation of the expanded product stably.

    摘要： The method of the present invention for producing a urethane-based thermoplastic elastomer composition foam comprises the steps of: adding and mixing 0.1 to 30 parts by weight of carbon dioxide (B) to 100 parts by weight of a urethane-based thermoplastic elastomer composition (A) in a molten state, wherein said urethane-based thermoplastic elastomer composition (A) comprises a urethane-based thermoplastic elastomer (A-1) and other thermoplastic elastomer (A-2) in an (A-1)/(A-2) ratio of 20/80 to 99/1 by weight, to form a molten urethane-based thermoplastic elastomer composition (C) which is in a state of a mixture of the urethane-based thermoplastic elastomer composition (A) and the carbon dioxide (B) (gas dissolving step); and lowering a temperature of said molten urethane-based thermoplastic elastomer composition (C) (cooling step). The present invention can produce the urethane-based thermoplastic elastomer foam of stable quality over a range from low foamed product to highly foamed product by adding a given quantity of carbon dioxide in the molten urethane-based thermoplastic elastomer quantitatively and stably. It can also produce the foam excellent in flexibility, thermal insulation and surface appearances. It is also excellent in safety, because of use of carbon dioxide in place of the common foaming agent of fluorochlorohydrocarbon or butane, thus causing no air pollution or destruction of the ozone layer.
