  • Patent number: 4987172
    Abstract: A flame-retardant synthetic resin composition comprising a thermoplastic resin selected from the group consisting of polyolefin, acrylonitrile-butadiene-styrene copolymer and ethylene-ethyl acrylate copolymer resins as a base polymer and, incorporated therein (A) a polyester fiber cut into a length smaller than 10 mm and/or a polyester powder having a particle size smaller than 10 mesh and (B) a polyphosphoric acid compound having a higher water resistance, wherein the amount of the thermoplastic resin is 40 to 95% by weight, the total amount of the components (A) and (B) is 5 to 60% by weight and the component (A)/component (B) weight ratio is in the range of from 5/1 to 1/20.

  • Patent number: 4675143
    Abstract: A shaped electroconductive thermoplastic resin composition article having a preferable surface appearance is produced by a process including (1) mixing a matrix resinous material containing 100 parts by weight of a thermoplastic resin and, optionally, 120 parts by weight or less of a flame x retardant additive and 40 parts by weight or less of a flame retardant synergistic additive, with 1 to 15% based on the weight of the matrix resinous material, of stainless steel fibers having a length of 2.5 to 7.5 mm and adhered to each other with a thermoplastic resinous adhesive to form a number of bundles; (2) kneading the resultant mixture at an elevated temperature at which the matrix resinous material is melted and (3) shaping the kneaded mixture into a desired form, the kneading the shaping procedures being carried out so that the stainless steel fibers are uniformly dispersed in the melted matrix resinous material and the dispersed stainless steel fibers have an average length of 0.5 to 2.0 mm.

  • Patent number: 4160711
    Abstract: An assembly of electrodes suitably for use in electrochemical processes, comprising a plurality of elongated conductive elements as electrodes arranged substantially in parallel in a vertical plane and spaced apart from each other. At least one elongated non-conductive element is interposed between every two adjacent conductive elements. Preferably, both the conductive and non-conductive elements are flexible and the assembly comprises a base fabric of non-conductive material and a plurality of conductive elements incorporated in said base fabric.
