    Abstract: Thermoplastic compounds are disclosed having functional filler of fly ash particles coupled to the thermoplastic resin via a coupling agent. A coupling agent of functional silane grafts on a backbone of the same polymer or a compatible polymer as the thermoplastic resin causes interaction of the fly ash particles with the thermoplastic resin to enhance physical properties, particularly Notched Izod impact resistance at room temperature and at ?40° C. The coupling interface between the fly ash particle and the coupling agent and the thermoplastic resin is so strong that there can be cohesive failure of the fly ash particle before there is adhesive failure of the fly ash particle from the coupling agent in the thermoplastic resin.

  • Publication number: 20140243442
    Abstract: A method of manufacturing a moulded article from expanded resin particles, the method comprising: placing the particles and a dielectric heat transfer fluid in a mould located between a pair of electrodes; generating a radio-frequency electromagnetic field between the electrodes; applying the electromagnetic field to the mould to dielectrically heat the heat transfer fluid and hence the particles; and heating the particles to a temperature sufficient to cause their surfaces to soften, so that the particles fuse, thereby to form the moulded article as shaped by the mould; preferably, wherein the radio-frequency electromagnetic field has a wavelength greater than an average dimension (or dimensions) of the moulded article.

    Abstract: Ultra high molecular weight polyethylene (UHMWPE) polymers that have an average molecular weight of at least 500,000 g/mol and an enthalpy of at least 190 J/g is provided. The UHMWPE polymer may include at least one comonomer. The UHMWPE polymer is used to form a membrane, that, when expanded, has a node and fibril structure. The UHMWPE membrane has an endotherm of about 150° C. associated with the fibrils in the membrane. The membrane has a percent porosity of at least 25%, and in exemplary embodiments, the percent porosity is at least 60%. Additionally, the UHMWPE membrane has a thickness less than 1 mm. An UHMWPE membrane may be formed by lubricating the UHMWPE polymer, subjecting the lubricated polymer to pressure at a temperature below the melting point of the UHMWPE polymer to form a tape, and expanding the tape at a temperature below the melting temperature of the UHMWPE polymer.

  • Patent number: 8785508
    Abstract: The present invention provides pre-expanded polypropylene resin beads comprising (A) a glycerin monoester of a C6 to C24 fatty acid and/or a polyglycerin monoester of a C6 to C24 fatty acid and (B) a glycerin diester of a C6 to C24 fatty acid(s) and/or a polyglycerin diester of a C6 to C24 fatty acid(s), in such a manner that a weight ratio [=(A)/(B)] between (A) and (B) in the polypropylene resin particles is 1.3 or more but 10 or less, and a total content [=(A)+(B)] is 0.3 parts by weight or more but 5 parts by weight or less with respect to 100 parts by weight of the polypropylene resin. The resin particles can be excellently used in in-mold foaming, without requiring washing with a chemical like nitric acid or metaphosphate soda, and can provide a polypropylene resin in-mold foamed product with good antistatic properties.

  • Publication number: 20140170922
    Abstract: Fibers that are formed from a thermoplastic composition that contains a polymer and high surface area nanostructures are provided. The fibers have a voided structure and low density while maintaining good strength characteristics. To achieve such a structure, a blowing agent in the thermoplastic composition is activated during extrusion to form bubbles in the fibers. The high surface area nanostructures in the formed fibers can be formed of or carry the blowing agent and can enhance the strength of the fibers and compensate for the non-load bearing voids of the fibers.
