Ceramic fiber blanket is high strength, needled insulating blanket that is made from 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.
Ceramic fiber blanket is completely inorganic and available in a variety of temperature grades, densities,and sizes.Ceramic fiber blanket can be folded, compressed and encapsulated to produce module.
1)Pipe wrap
2)Furnace and kiln back-up insulation
3)Chimney insulation
4)Annealing furnace linings
5)Process heater linings
