  • Patent number: 8604092
    Abstract: A polymeric complex supporter for controlling oxygen-released compounds (PCS-ORCs) and a method for manufacturing the same is disclosed. PCS possesses a porous surface and internal coralloid-like channel structure that can accommodate ORCs with a high ratio (up to 92 wt %) to polymers. In applications, the PCS-ORCs can be shaped as various types and be coupled with other solids that could be used as delivery tools. As PCS-ORCs is delivered into a water-containing environment, water molecules can diffuse into the internal channels through the surface pores and then react with ORCs. Due to the tunable structure properties of PCS, the produced oxygen can be release out through the surface pores for one to six months long. In comparison with powder-type ORCs, PCS-ORCs can exhibit better application potentials in terms of time-release technology, oxygen delivery and environmental responsibility.

  • Patent number: 6235805
    Abstract: A process for producing static-free synthetic rubber includes mixing acrylonitrile-butadiene, Anti-static agent, Activated zinc oxide, Zinc stearate, HI-sil (EPDM), Plasticizer, and Stearic Acid prior to a kneading process at 140 degrees Celsius for 8 to 12 minutes. (DCP) Peroxides and Blowing agents are added to the kneeing mixture two minutes before the end of the kneeding process. After the kneeding process, the resultant mixture is fed through rollers to form a sheet of the synthetic rubber. The sheet is then cut into appropriately-sized pieces and put into a mold, where the pieces are subjected to high pressure and a temperature of 160 degrees Celsius. The pieces are then left to cool, and then be used for articles such as static-free footwear.

  • Patent number: 6187427
    Abstract: Three-phase composite materials system having a low dielectric constant and physico-chemical properties suitable for IC fabrication conditions, and a method for making such materials, are disclosed. The three-phase composite material includes an organic phase, an inorganic phase and a void phase. The organic phase is in the form of an organic polymer matrix, the void phase is represented by microporosity present in the matrix, and the inorganic phase is implemented as inorganic particles that are coupled, via a coupling agent, to the organic matrix. The low dielectric constant of the composite is attributable to the microporous organic polymer matrix. The inorganic particles are responsible, at least in part, for providing thermal stability and other required physico-chemical properties to the composite.

  • Patent number: 6075063
    Abstract: A method for foaming or foam-coating components is used for foaming hollow cavities of double-walled or multiple-walled components or foam-coating component parts with decorative surfaces so as to improve haptic properties of component parts. A material is introduced or applied in an unfoamed state to be foamed through the use of microwave energy. In order to achieve high dielectric losses and to ensure that the heat effect is evently distributed and essentially restricted to the material to be foamed, the material is adjusted in a polar manner by addition of certain substances such as conductive soot. Reflecting agents are used to improve the distribution and effect of the microwaves. The method ensures fully foamed hollow cavities and foam layers of uniform thickness. A foamable material for foaming or foam-coating components is also provided.
