  • Patent number: 6457917
    Abstract: The method of forming a light-weight, fiber-reinforced, particularly glass fiber-reinforced-thermoplastic resin product includes the steps of melting and mixing thermoplastic resin pellets containing parallely oriented fibers 2-100 mm long, injecting the melted resin into a cavity which is closed so that its volume is smaller than that of the final molded product, and, before or after the resin injection is completed, opening the cavity until its volume is equal to that of the final molded product. Unlike the conventional injection-molded products, this product does not require a foaming agent and, if it uses any, requires only a small amount of foaming agent. The product thus formed is light in weight and has fibers uniformly entangled inside, providing an excellent appearance of the surface. Further a skin layer is formed over the surface. These features combined with the reinforcement by the glass fibers offer high strength and high stiffness.

Further, it is preferable that the core layer contains an additive resin, which is compatible with a binder resin that is used for the electrophotographic toner and can give an elasticity to the core layer when the additive resin and the binder resin are dissolved with each other. According to the arrangement, it is possible to utilize as a raw material a nonstandard toner, which is produced during a manufacturing process of the electrophotographic toner, but cannot be used as a commercial product, and a discard toner, which has been used in an image forming apparatus of an electrophotographic method, thereby realizing a resin molding product of a high quality at a low cost, while the resin molding product can improve its impact resistance by use of the additive resin.

    Abstract: There is a need for polymers that offer a high level of heat and ultraviolet light resistance. It is particularly critical for polymers that are utilized in making skin compounds for automotive instrument and door panels to display excellent heat and ultraviolet light resistance. Polymer blends having such characteristics can be made by blending certain rubbery polymers with halogen containing polymers, such as polyvinyl chloride (PVC). There is currently a demand for halogen-free polymers having such characteristics. This invention discloses a rubbery polymer that can be blended with polyolefins, such as polyethylene or polypropylene, to make leathery compositions having good heat and ultraviolet light resistance. The rubbery polymer of this invention is comprised of repeat units which are comprised of (a) butyl acrylate, (b) an alkoxyalkylene acrylate, (c) styrene, (d) a half ester maleate soap, and (e) a crosslinking agent.

    Abstract: The present invention provides microcellular articles, as well as methods and apparatuses for producing polymeric foams, and, in particular microcellular material. The methods involve forming a gas blanket within a polymer processing die that prevents contact between the polymer melt and surfaces of the die during extrusion. In one set of embodiments, the gas blanket is provided by gas diffusing out of surfaces of the nucleated polymer material. In other embodiments, the gas blanket is formed by introducing a gas from an external source into the polymer flow channel within the die. The dies, according to the invention, are specially configured to generate and to support the gas blanket. The extruded foams are free of surface defects that, typically, arise from contact between the polymer melt and the die surfaces.

    Abstract: A method for forming an angled plastic article of varying density whereby a blowing agent is added to a plastic material and the material is injected into a mold cavity of a mold unit. The interior walls of the mold cavity are maintained at a temperature sufficient to prevent the outer skin of the hardening plastic article from producing gas bubbles. The volume of the mold cavity is increased to allow bubbles to produce and uniformly distribute themselves throughout the mold cavity and then a reconversion phase is instituted whereby the desired density of the finished plastic article is achieved without voids or aberrations appearing in the surface of the plastic article. The mold unit is provided with extensible beveled edges which extend and retract as the mold cavity is enlarged and compressed. By this method, a resulting plastic article of varying density is produced having grooves running the length of the article.
