LUYANGWOOL® Thermal Insulation Ceramic Fiber Blanket / RCF Blanket
Luyangwool® ceramic fiber blanket is high strength, needled insulating blanket that is made from Luyangwool® ceramic fiber bulk. The combination of long spun fibers and needling operation produce tough, resilient and strong blankets, which resist tearing both before and after heating.
Luyangwool® ceramic fiber blanket is completely inorganic and available in a variety of temperature grades, densities, and sizes. Luyangwool® ceramic fiber blanket can be folded, compressed and encapsulated to produce module.
