摘要： Disclosed is a method for providing accelerated release of a blowing agent from a solid, non-perforated plastic foam. The method relates (a) providing the solid, non-perforated plastic foam having the blowing agent and a permeability modifier therein and (b) perforating the foam at its surface to form a multiplicity of channels extending from the surface into the foam. The channels are in gaseous communication with the environment outside the foam and provide accelerated release of blowing agent.

摘要： A wrist support (10) and method for constructing the wrist support is described. The wrist support includes a base (12) with a cushion layer (14) mounted on the top surface (12A) and an outer covering (16) surrounding the base and cushion layer. The bottom surface (12B) of the base has an adhesive (13) which is protected by a release paper (15). The release paper is removed in order to secure the ends (16A) of the outer covering to the base. The wrist support is constructed from a sheet of base material (36) and a sheet of cushion material (38) which are cut into a wrist support preform (26) in a mold (20). The sheets are inserted between a first half (22) and a second half (32) of the mold with the base adjacent the second half of the mold. The first half of the mold is then moved downward into contact with the second half which causes the second half to also move downward and which enables the plunger (34) of the second half to extend into the indentation (24) of the first half. As the plunger enters the indentation the cutting edges (34C) of the sidewalls (34A) of the plunger cut the sheets of material into the shape of the wrist support. The first and second halves of the mold continue to move downward causing the plunger to compress the cut base and cut cushion layer against the top (24B) of the indentation with the edges (12C) of the base adjacent the curved portion (24C) of the indentation.

摘要： Blanks serving for the production of insulating material and folding packs have to be provided with folding and bending lines. These folding and bending lines in the plastic foam must not break when the blank is folded. This is achieved according to the invention by embossing the folding and bending lines for forming the blank into the "fresh" web of material which for the most part still contains expanding agent. The folding and bending lines formed in this way have surprisingly proved to form durable hinge lines in the plastic foam material and make it possible to fold up the blank for forming a folding carton without it breaking or cracking.

摘要： A method is provided for making a lightweight composite panel in which an outer skin is developed by spraying a heat curable reactive urethane formulation onto a contoured heated surface of a mold cavity of a press mold and maintained thereon in a semi-cured state. A substrate-forming foam layer impregnated with a hardening compound is positioned against a second foam layer and the layers in turn laid over the semi-cured urethane skin. The foam layers are urged together within the mold under heat and pressure at a temperature sufficient to accelerate activating of the hardening compound to render the substrate-forming foam layer relatively stiff, hard and self-supporting and less compressible than that of the second foam layer, and to bond the foam layers to one another at their interface, while forcing the semi-cured skin material into interstices of the second foam layer and thereafter curing the skin producing a bond between the skin and the second foam layer.

摘要： A method and apparatus are provided for densifying expanded polymer materials such as styrofoam for transportation between collection centers and manufacturing plants for recycling. The method and apparatus use only pressure and time with no addition of heat which would render the expanded polymers non-recyclable or impure. The method and apparatus rely on mechanical creep over a relatively long time with no binding materials or restraining packaging which would have to be removed prior to remanufacturing. The method and apparatus compress the expanded polymer material in three directions and confine it for the period of time required for the polymers to mechanically creep to a permanent block having a high density. The high density will not expand significantly after the block is released, unconfined into the ambient. The blocks may be easily loaded for efficient, economical transportation.

摘要： A headliner for mounting in the passenger compartment of a vehicle is formed from a plurality of layers of materials including foamed polyurethane, fiber glass and scrim. The layers are bonded together under heat which cures an incorporated thermosetting resin. The thermosetting resin freezes the assembled laminate conforming to the configuration of the lowermost mold. After setting of the resin the flexible laminate is trimmed to the desired shape at its periphery.

摘要： A resin laminate of the invention includes a sheet laminate including a skin, which is securely joined with a foamed bead base by heating. The resin laminate is manufactured according to the following steps. The foamed bead base and the sheet laminate consisting of the skin, a foam layer, and a thermoplastic resin film are prepared separately. The thermoplastic resin film is made of a resin material which thermally adheres to both the foam layer and the foamed bead base and has a softening temperature lower than those of the foam layer and the foamed bead base. The thermoplastic resin film is softened by heating the sheet laminate, which is then softened by heating the sheet laminate, which is then pressed against and bonded to the foamed bead base by vacuum molding or press forming. The thermoplastic resin film thermally adheres to both the foam .layer of the sheet laminate and the foamed bead base, thus joining the sheet laminate with the foamed bead base.

摘要： Rigid foam insulation boards and thin flexible fibrous sheets or strips are stacked in alternating layers with adhesive between the layers, and the stack is compressed while the adhesive cures to form a rectangular core panel or billet. In one embodiment, the parallel spaced sheets or strips extend diagonally of the panel or billet, and each billet is cut through the alternate layers of foam and fibrous sheets and along parallel spaced planes to form a plurality of core panels. The core panels are adhesively bonded between skins of rigid sheet materials to form laminated sandwich panels with the fibrous strips connecting the skins. The above stacking and curing steps are also performed with core panels in place of insulation boards to form a billet which is cut to form core panels with grid-like webs, and grid-like core panels are used to form a billet with the webs extending in X-Y-Z directions. Billets are also formed with core panels stacked in a step-like manner and then cut along inclined parallel planes to provide core panels with truss-like webs, and billets are formed with adjacent rigid foam boards having different densities and thicknesses, Resilient foam panels are used in place of or with the fibrous sheets for producing core panels which may be curved, and the foam between the webs of grid-like core panels is recessed to expose the webs for bonding surface materials such as stucco to the core panels.
