  • Patent number: 7300546
    Abstract: A cellulose fiber having extended biostability and the method of its manufacture are described. While prior treatments of cellulose with biotoxic metal compounds have given improved resistance to decay, these treatments have not been entirely satisfactory where the fiber had to be refined before use. Refining energy was very high and fiber length loss was substantial. Treatment of cellulose fiber with dideyldimethylammonium chloride (DDAC) or bromide (DDAB), these materials in combination with low levels of copper, or low levels of copper alone, has given a product with very good biostability without a major increase in refining energy or loss of fiber length. The treated fiber is particularly advantageous as a reinforcing component for cement board products.

  • Patent number: 7267873
    Abstract: Fiber reinforced concrete has thin steel wire of diameter between 0.05 and 0.3 mm such as cut from recycled vehicle tires. To avoid the problem of balling when mixing, two alternatives are suggested. The first consists of strands of fiber, which demonstrate excellent bond characteristics. The second consists of a mixture of fiber lengths and thicknesses, giving a wide distribution of l/d ratios not exceeding 250, which has the effect of reducing balling tendency so that significant densities can be achieved.

  • Patent number: 6852412
    Abstract: A fire and thermal insulative wrap for protecting building wires and cables is provided comprising a layered construction of a support substrate and a coating, thereon, of an intumescent material. Optionally, a third ceramic layer is provided for added fire protection and electrical properties. Wires and cables constructed to include the wraps are cost effective because construction can include the substitution of low cost polyolefin resins and compounds for fluorocarbon resins and smoke suppressed PVC compounds. The new constructions based on polyolefin components advantageously produce lower levels of smoke and toxic and corrosive gases during a fire event when compared with the halogen based PVC and fluorocarbon systems. Moreover, the superior fire and thermal protection provided adds safety gained from increased circuit integrity. Finally, the wrap thickness being slight does not add significantly to cable size and therefore promotes an installation advantage.

  • Patent number: 6805956
    Abstract: The present invention relates a process for manufacturing polymer coated wire and cable and an electrically conductive wire having a metal core and an outer electrically-insulative, polymer coating capable of withstanding temperatures as high as 150° C., wherein the polymer composition contains polyphenylene sulfide, a polymeric grafting agent and an ethylene copolymer. The polymeric grafting agent is a copolymer of at least about 50% by weight ethylene, about 0.5% to about 15% by weight of a reactive comonomer (e.g. unsaturated epoxide of 4-11 carbon atoms) and the ethylene copolymer comprises at least about 50% by weight ethylene and about 1% to about 35% by weight of an acid-containing unsaturated mono-carboxylic acid comonomer. The molar ratio of the reactive comonomer in the polymeric grafting agent to the unsaturated mono-carboxylic acid comonomer of the ethylene copolymer is to be maintained between 1.0 and 5.5 in order to achieve the desired polyphenylene sulfide wire coating properties.

  • Patent number: 6800367
    Abstract: Fire retardant and heat resistant yarns, fabrics, and other fibrous blends incorporate one or more fire retardant and heat resistant strands comprising oxidized polyacrylonitrile and one or more strengthening filaments such as metallic filaments (e.g., stainless steel), high strength ceramic filaments, or high strength polymer filaments. Such yarns, fabrics, and other fibrous blends have a superior tensile strength, cut resistance, abrasion resistance, LOI, TPP and continuous operating temperature compared to conventional fire retardant fabrics. The yarns, fabrics, and other fibrous blends are also more soft, supple, breathable and moisture absorbent and are therefore more comfortable to wear, compared to conventional fire retardant fabrics. The inventive yarns may be woven, knitted or otherwise assembled into a desired fabric or other article of manufacture.
