  • Patent number: 10232598
    Abstract: A skinned panel for stably molding a thin skin material and a molding method thereof. An extruding device is configured to extrude a pair of multilayered resin sheets, each of which has a lamination structure of an inner layer made of a foamed resin and an outer layer made of a non-foamed resin that is changed into a skin material of a sandwich panel as a skinned panel. The pair of the resin sheets is abutted to the circumferential part of the pair of the split molds for producing sealed spaces. The sealed spaces are sucked for pressing the pair of the resin sheets onto cavities of the pair of the split molds. Accordingly, the pair of the resin sheets is formed in a shape substantially identical to the outline of the sandwich panel.

  • Patent number: 9157005
    Abstract: The method of foaming and applying a sealing material is characterized by comprising the steps of hot-melting the sealing material; mixing nitrogen gas into the melted sealing material under a predefined pressurization; discharging the resultant mixture at a predefined pressure into the air to thus foam the mixture and simultaneously apply it to a place necessary to seal, thus making a sealing foam; and curing this sealing foam by ultraviolet rays. By this method, the sealing material does not involve flowing after applied, and shows an excellent sealing performance even under severe heat resistance conditions, and also can make good independent cells inside even when used in a foamed condition.

  • Patent number: 8580898
    Abstract: The present invention relates to a copolymer polyester resin and a molded product using the same, and more specifically to a copolymer polyester resin that contains 10˜80 mol % of 1,4-cyclohexane dimethanol, 0.1˜50 mol % of a diol compound expressed as HO—(CH2)a—CO—(CH2)b—OH (where a and b are integers in the range 1˜5), and ethylene glycol or other diols so that the sum of its entire diol composition is 100 mol % based on dicarboxylic acid. The copolymer polyester resin of the present invention enables reduction of cycle time, improvement of product processability and prevention of PET bottle deformation during mold processing with a heat-shrinking label by complementing low temperature shrinkage, maintaining a high shrinkage rate, and reducing shrinkage stress.

  • Patent number: 8568632
    Abstract: A process for making closed-cell, alkenyl aromatic polymer foams using nano-particle nucleation agents to control the cell morphology of the resulting foam includes forming a polymer melt at a temperature above the polymer glass transition temperature (for crystal polymers) or the polymer melt point (for amorphous polymers); incorporating selected nano-particles into the polymer melt; incorporating blowing agents into the polymer melt at an elevated pressure; optionally incorporating other additives, such as flame retardants, into the polymer melt; and extruding the polymer melt under conditions sufficient to produce a foam product having a desired cell morphology, characterized by parameters such as reduced average cell size range and/or increased asymmetry of the cells.

  • Publication number: 20130281835
    Abstract: An embryo transfer catheter or other medical device has a shaft extruded with two layers. The outer layer is relatively thick and contains gas bubbles sufficient to increase the visibility of the catheter under ultrasound observation but with a density that allows material within the catheter to be viewed by the eye. The inner layer is relatively thin and is free of bubbles so that it provides a smooth bore to the catheter.

  • Patent number: 8480836
    Abstract: A double-sided, slip resistant material is produced using a blown film process which produces a film having an interior heat sealable layer, a core layer of flexible polyolefin and an exterior polyolefin elastomer layer in combination with a blowing agent and optionally grit to produce a double-sided slip resistant material. A number of rollers are provided after nip rollers have fused the film together, and which form part of a machine direction orienter (MDO) that is used in line in the manufacturing process to heat, and then cool and condition (anneal and relieve any stresses and/or thickness inconsistencies in the film) prior to the film being wound onto a roll for storage.

  • Patent number: 8398904
    Abstract: The present invention relates to a microcellular foam of a thermoplastic resin and a method for preparing the same, and more particularly to a microcellular foam comprising a skin layer having a porosity of below 5% and a core layer having a porosity of at least 5%, wherein the thickness of the skin layer accounts for 5 to 50% of the entire foam, and a method for preparing the same. The microcellular foam of the present invention is advantageous in that it has a thicker skin layer and smaller and uniform micropores in the core layer, compared with conventional microcellular foams, while having mechanical properties comparable to those of conventional non-foamed sheets.

  • Patent number: 8376149
    Abstract: The invention relates to the preparation of a crosslinked polymeric film bearing ionic groupings. The process consists in extruding a material comprising at least one prepolymer, in polymerizing said material after extrusion, and in subjecting the extruded material to a chemical reaction for grafting ionic groupings. The prepolymer comprises repeating units each comprising at least one aromatic group GA and at least one functional group GF; it bears at least one group GP which is polymerizable thermally at a temperature greater than the extrusion temperature, or photochemically, and also at least one reactive group GR which allows the grafting of ionic groupings. The films are useful as a membrane for fuel cells or electrodialysis, as an electrolyte of a lithium battery, of a supercapacitor or of an electrochromic device, or as an ion exchange membrane.
