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,
