Used in cable applications, this technology provides low heat release rates. Nanocomposites show tremendous property enhancements compared to pure polymers. A very interesting property exhibited by polymer-layered silicate nanocomposites concerns their ability to promote flame retardancy at very low filling levels. The formation of a thermal insulating and low permeable char to volatile combustion products caused by a fire is responsible for these improved properties. The well-known organoclays (modified layered silicates) are often added at a level between 2% and 10% weight 关键词: carbon nanotubes;clay;filled polymers;flame retardants;nanocomposites;silicon compounds;thermal insulation;multiwall carbon nanotubes;flame retardants;nanofillers;cable applications;polymer layered silicate nanocomposites;thermal insulation;volatile combustion products;organoclays;modified layered silicates;low permeable char;C;SiO2
