  • Patent number: 5268134
    Abstract: Hoses are often reinforced with fabric to improve their performance characteristics, such as burst strength. By utilizing the technique of this invention, hose which has a high level of burst strength can be manufactured without including continuous yarn reinforcement. This invention specifically reveals a process for manufacturing a hose which involves the steps of (1) extruding a rubber composition into the form of a tube, wherein the rubber composition contains (a) an EPDM alloy comprised of (i) standard EPDM rubber, (ii) an EPDM rubber having thermoplastic side chains grafted thereto, and (iii) dispersed thermoplastic wherein the thermoplastic is selected from the group consisting of nylons, polyesters, and polyphenylene oxides, (b) an EPDM rubber, (c) carbon black, (d) at least one curative, (e) zinc oxide, (f) a processing oil, and (g) stearic acid; (2) shaping the tube into the geometric form desired for the hose; and (3) curing the rubber composition at a temperature within the range of 130.degree. C.

  • Patent number: 5218020
    Abstract: The invention relates to elastomers and articles reinforced with 5 to 30 phr Chitosan particles having a diameter of 0.5 to 75 microns. In an illustrated embodiment, the Chitosan may be modified with an oxygen reactive group or a nitrogen reactive group to make the Chitosan more reactive with an elastomer. Also provided is an economical method of incorporating very fine Chitosan particles into an elastomer matrix. In the method Chitosan is dissolved in an acid and mixed with a coagulating liquid (for coagulating latex), and the mixture of chitosan/coagulating liquid is mixed with a latex solution to provide an elastomer/chitosan composite. The elastomer/chitosan composite may be used as formed or it can be used as a masterbatch and mixed with more elastomer.

  • Patent number: 5077338
    Abstract: A method of preparing a fiber reinforced elastomer by forming fibers therein in-situ and an elastomer made thereby are provided. In the method, a fiber forming material, preferably a high performance polymer, is dissolved in a compatible solvent to form a solvent/polymer mixture, and the mixture is added to the elastomer during compounding or mixing. The polymer is quickly dispersed into the elastomer, and the solvent rapidly evaporates. The shear of the mixer causes elongation of the polymer into fibers. The fibers may also be oriented by the shear of the mixer.
