摘要： A two-dimensional integral net having a nap in form of relatively long fibres which are integral with the net and protrude from the edges which surround the apertures of the net.A method of producing this net from a film is by heating selected areas of the film to a molten state and dragging out this molten material into fibres to leave apertures in the film while controlling the fibre-dragging by cooling with an air jet.

摘要： A method for making closures resembling natural cork for sealing liquid product containers is described. A strand of expandable plastic material is injected into each mold cavity and is permitted to collect in that cavity in randomly oriented groups of coils which expand to fill the cavity and coalesce to create randomly oriented grain lines on the surface of the closure resembling the appearance of natural cork. Also described are methods of molding the closures which preclude the formation of leakage channels on the closure surface and preferred blends of plastic resins and pigment particles used to achieve the cork-like appearance.

摘要： A method for decreasing the density of a substantially closed-cell thermoplastic resin foam material by the secondary expansion thereof. The method comprises increasing the gas pressure within the cells, retaining that elevated cell pressure for prolonged periods and then heating the foam material above its heat plastifying temperature to cause secondary expansion thereof. In an example, a low density polyethylene material was foamed to produce a foam with a density of approximately 0.085 grams per cubic centimeter. This foam was then pressurized with nitrogen and afterward secondarily expanded to produce a foam with a density of approximately 0.036 grams per cubic centimeter.

摘要： This application is directed to light-weight and hard foam materials. The foams of this invention are prepared by extruding thermoplastic crystalline plastics in the presence of highly volatile organic liquids as the foaming agents. In accordance with the present method crystalline polyolefins, in the presence of polybutadiene, ethylenevinylacetate copolymers, ethylene-propylenes and/or ethylene-propylene terpolymer rubbers, and optionally radical formers such as suitable peroxides, azidene, sulfonyl azidene or the like, and inhibitors for radical decomposition, such as triallylcyanurate or an acrylate selected from the group consisting of trimethylolpropane-trimethacrylate, allyl-methacrylate, tetrahydrofurfurylmethacrylate, triethyleneglycol-dimethacrylate, polyethyleneglycol-dimethacrylate or the like, are converted into foam-like molded bodies by means of a highly volatile organic liquid foaming agent. The foaming agent is employed in an amount of from about 5 to about 30% by weight, based on the weight of the polyolefins. The foaming agent and the polyolefins are mixed in an extruder at a temperature of from about 180.degree. to about 280.degree. C., and at a pressure which is greater than the vapor pressure of the foaming agent. The mixture is subsequently extruded.

摘要： A cellular polymeric resin sheet, slab or the like is produced by filling a pressure resistant receptacle having a cover directly releasably locked thereto with a uniform mixture of a resin such as polyvinyl chloride, a finely divided heat activated first gas generator and preferably a water activated second gas generator together with other additives such as plasticizers, stabilizers, etc. The closed receptacle is heated to effect the gelation and fusion of the resin and the activation of the first gas generator to produce a high density uniform small pore cellular resin body embryo under high pressure in the receptacle. The receptacle and embryo are cooled, the receptacle opened and the embryo removed and subjected to a high humidity atmosphere, preferably at elevated temperature to activate the second gas generator and react therewith. The receptacle may be provided with passageways for the circulation of heating and cooling media and may be provided with heat transfer fins which strengthen the receptacle and is heated and cooled by immersion or exposure to hot and cold fluids. The receptacles may carry electric heating elements for their heating.
