FLAME RETARDANT RESIN COMPOSITION, AND INSULATING ELECTRIC WIRE, TUBE, HEAT-SHRINKABLE TUBE, FLAT CABLE AND DC HIGH-TENSION ELECTRIC WIRE ALL MADE OF THE COMPOSITION

摘要

(1) A FLAME RETARDANT RESIN COMPOSITION COMPRISING 100 PARTS BY WEIGHT OF THERMOPLASTIC RESIN, 100 TO 250 PARTS BY WEIGHT OF METAL HYDROXIDE, AND THEIR 5 TO 50 PARTS BY WEIGHT OF ACETATE OR 5 TO 80 PARTS WEIGHT OF CALCIUM CARBONATE. (2)AN INSULATED WIRE PROVIDED WITH AN INSULATING LAYER MADE OF THE FLAME RETARDANT RESIN COMPOSITION. (3) A THIN-WALL HIGH-STRENGTH INSULATED WIRE OBTAINED BY HAVING A CONDUCTOR WITH AN OUTER DIAMETER NOT GREATER THAN 1.0MM COVERED WITH THE FLAME RETARDANT RESIN COMPOSITION WITH A THICKNESS FROM 0.1MM TO NOT GREATER THAN 1.0MM. (4) AN INSULATING TUBE AND A HEAT-SHRINKABLE TUBE OBTAINED BY MOLDING THE FRAME RETARDANT RESIN COMPOSITION INTO A TUBULAR FORM. (5) A FLAT CABLE OBTAINED BY ENCLOSING A PLURALITY OF CONDUCTORS ARRANGED IN PARALLEL IN AN INSULATING COVER AND THE FLAT CABLE OBTAINED BY FURTHER LAMINATING AT LEAST ONE FACE OF THE INSULATING COVER WITH A FILM MADE OF POLYMERIC MATERIAL. (6) A HIGH-VOLTAGE DC ELECTRIC WIR PROVIDED WITH AN INSULATING COVER MADE OF THE FLAME RETARDANT RESIN COMPOSITION. (7)ARTICLES AS MENTIONED ABOVE HAVING THE FLAME RETARDANT RESIN COMPOSITION CROSS-LINKED, ESPECIALLY IRRADIATED WITH AN IONIZING RADIATION. INSULATED WIRE, TUBE, HEAT-SHRINKABLE TUBE AN FLAT CABLE HAVING EXCELLENT MECHANICAL STRENGTH AND FLAME RETARDANCE WITHOUT GENERATING ANY HARMFUL GAS, WHEN BURNING, ARE PROVIDED. THE INSULATED WIRE AND THE FLAT CABLE ARE SUITABLY USED FOR INNER WIRING OF CONSUMER''S ELECTRONIC DEVICES, AUTOMOBILES AND SHIPS AND SO ON.
