CERAMIC FIBER BLANKETS

NR blankets are made from selected high quality spun ceramic fiber, double sides mechanically needling makes it high strength and surface integrity

NR blankets have a good character of superior insulating performance, light weight, flexibility, resilience and chemical resistance, low thermal conductivity, low heat storage,
