  • Patent number: 8889046
    Abstract: A method comprising injection molding a plastic part from a polymer formulation comprising an injection moldable thermoplastic and an additive, wherein the additive has a decomposition temperature that establishes a maximum processing temperature for the polymer formulation. The additive will thermally decompose to generate gaseous products causing visible bubble formation in the surface of the plastic part in response to exposure to a processing temperature that exceeds the decomposition temperature of the additive. A suitable additive may be, for example, selected from oxalates, carbamic acids, carbonic acids, diazocarbonyl compounds, and combinations thereof.

  • Patent number: 8877106
    Abstract: There are provided a forming device capable of drying at a high speed and of manufacturing a thermosetting resin foam plate more efficiently and stably without multilayering any unnecessary surface material, and a method of efficiently manufacturing a thermosetting resin foam plate therefor. A thermosetting resin foam plate is manufactured by: mixing a resin composition containing at least a thermosetting resin, a foaming agent and a curing agent in a mixer; continuously discharging the resin composition on a traveling air-permeable and flexible surface material, and at the same time covering the upper surface of the resin composition with an air-permeable and flexible surface material; and passing the covered resin composition through a forming device equipped with conveyors having apertures having an aperture area ratio of 15% or more and 80% or less to form and cure the resin composition.

  • Publication number: 20140318034
    Abstract: A method of making a rounded ridge cap includes providing an intermediate product comprising a plurality of sections arranged side by side and integrated as a single body of an asphaltic foam material, each of the plurality of sections comprising a rounded top surface, the plurality of sections comprising first and second sections immediately neighboring each other. The first section comprises a first side and the second section comprises a second side integrated with the first side to form a bridge portion between the first and second sections. The method further includes bending the first section with respect to the second section about the bridge portion, thereby forming a rounded ridge cap comprising a rounded exterior surface. The rounded top surfaces of the first and second sections form together the rounded exterior surface of the rounded ridge cap.
