20140138119 | NON-HALOGEN MULTILAYER INSULATED WIRE AND METHOD FOR PRODUCING THE SAME - A non-halogen multilayer insulated wire includes a conductor, an inner layer covering the conductor, and an outer layer formed on the external surface of the inner layer. The inner layer includes a polyolefin resin composition including 60 to 95 parts by mass of a high density polyethylene, 5 to 40 parts by mass of an ethylene copolymer, and 0.1 to 1 part by mass of a metal damage inhibitor. The outer layer includes a polyester resin composition that includes a base polymer mainly including a polyester resin, and further includes, relative to 100 parts by mass of the base polymer, 50 to 150 parts by mass of a polyester block copolymer, 0.5 to 5 parts by mass of a hydrolysis inhibitor, 0.5 to 5 parts by mass of an inorganic porous filler, and 10 to 30 parts by mass of magnesium hydroxide. | 05-22-2014 |
20140370286 | HALOGEN-FREE FLAME-RETARDANT WIRE - A halogen-free flame-retardant wire includes a conductor, and a single insulation layer or a plurality of insulation layers formed by covering an outer periphery of the conductor with a halogen-free flame-retardant resin composition. The single insulation layer or an outermost insulation layer of the plurality of insulation layers includes a halogen-free flame-retardant resin composition including a base polymer including an ethylene-vinyl acetate copolymer (EVA) of not less than 25 mass % in a vinyl acetate content (VA content) or a polyethylene (PE) with a melting peak at 115 to 140° C. measured by a differential scanning calorimetry (DSC), and a metal hydroxide mixed in an amount of 150 to 300 parts by mass per 100 parts by mass of the base polymer. A mass change rate of the single insulation layer or the outermost insulation layer after 24-hour immersion in xylene at 110° C. is not more than 420%. | 12-18-2014 |
20140370315 | NON-HALOGEN FLAME RETARDANT ELECTRIC WIRE CABLE - A non-halogen flame retardant electric wire cable includes a conductor, at least one insulating layer formed on an outer periphery of the conductor by coating the conductor with a non-halogen flame retardant resin composition, and a sheath formed on an outer periphery of the outermost insulating layer by coating the outermost insulating layer with the non-halogen flame retardant resin composition. The non-halogen flame retardant resin composition includes a base polymer including any one of ethylene-vinyl acetate copolymer having a vinyl acetate content of 25% by mass or more and polyethylene having a melting peak temperature of 115° C. to 140° C. as measured by DSC and a metal hydroxide. Ratios of the changes in the mass of the sheath and the outermost insulating layer which occur when the sheath and the outermost insulating layer are immersed in xylene heated at 110° C. for 24 hours are 420% or less. | 12-18-2014 |
20150030853 | CROSSLINKABLE HALOGEN-FREE RESIN COMPOSITION, CROSSLINKED MOLDED ARTICLE, INSULATED WIRE AND CABLE - A crosslinkable halogen-free resin composition includes a base polymer including at least one type of ethylene-vinyl acetate copolymer (EVA) and an acid-modified polyolefin resin having a glass-transition temperature (Tg) as measured by DSC of not more than −55° C. at a mass ratio of 70:30 to 99:1, and a metal hydroxide included in an amount of 100 to 250 parts by mass per 100 parts by mass of the base polymer. The at least one type of EVA has a melting temperature (Tm) as measured by DSC of not less than 70° C. The base polymer includes 25 to 50 mass % of a vinyl acetate (VA). | 01-29-2015 |
20150371735 | INSULATED WIRE - An insulated wire includes a conductor, and an insulating cover layer including an inner layer on an outer periphery of the conductor and an outer layer on an outer periphery of the inner layer. The inner layer includes a halogen-free resin composition including base polymer (A), which includes a first ethylene-α-olefin copolymer (a1) and a second ethylene-α-olefin copolymer (a2) at a ratio of 50:50 to 90:10, the first ethylene-α-olefin copolymer (a1) having a density of not less than 0.864 g/cm3 and not more than 0.890 g/cm3, a melting point of not more than 90° C. and a melt flow rate of not less than 1 g/10 min and not more than 5 g/10 min, and the second ethylene-α-olefin copolymer (a2) having a melting point of not less than 55° C. and not more than 80° C. and a melt flow rate of not less than 30 g/10 min. | 12-24-2015 |
