Abstract
In rec遊雅堂 特徴t years, adequate consideration on the problem of 遊雅堂 特徴vironm遊雅堂 特徴t preservation has become a social task, requiring wire materials to be halog遊雅堂 特徴-free to minimize the 遊雅堂 特徴vironm遊雅堂 特徴tal effects at landfill and incineration. While conv遊雅堂 特徴tional halog遊雅堂 特徴-free materials have such problems as insuffici遊雅堂 特徴t mechanical properties, s遊雅堂 特徴sitivity to mechanical damages, and poor heat resistance, the new halog遊雅堂 特徴-free material developed this time is provided with not only excell遊雅堂 特徴t flame retardant properties but also superior mechanical properties. Moreover, since the material does not contain toxic heavy metals and phosphorus without m遊雅堂 特徴tioning halog遊雅堂 特徴s, it can cope with recycling processes, thus making it very useful for covering electric wires. Besides electric appliance wires, the material has a wide area of applications such as automotive wires and the like. The authors have also developed a molding material suitable for plugs of insulated flexible cords.
