Ceramic Fiber felt is a kind of lightweight and flexible refractory fiber insulation material made from Bulk Fibers, processed by vacuum forming.Ceramic Fiber Felt is a multi-functional products combines excellent tensile and strength together, which is widely used in various furnaces and boilers wall lining and back lining.
Features:
● Low thermal storage, low thermal conductivity
● Excellent chemical stability
● Excellent thermal stability and thermal shock
Application:
● Industrial furnace lining
● Heating equipment wall lining and back lining
● Ceramics kilns thermal insulation
● Molten metal thermal insulation, etc..
Classification Temperature：1050℃， 1260 ℃，1360℃，1400℃， 1430 ℃
Specifications and packaging
The packaging of fiber felt is carton packaging, which is placed on the pallet and then wrapped in plastic wrap.
