Refractory Ceramic Fiber Blanket
【Product Introduction】
Refractory ceramic fiber blanket is a high-temperature thermal insulation material, widely used in industrial furnace linings, kiln insulation and high-temperature pipe insulation.
【Product Features】
Low Thermal Conductivity
The thermal conductivity of refractory ceramic fiber blanket is as low as 0.035W/m·K (at 400℃), which effectively reduces heat loss and improves the insulation efficiency of equipment.
High Tensile Strength
The fibers are reinforced by needle punching, with a tensile strength of more than 40kPa, and are not easy to deform or break during transportation and installation.
Wide Range Of Application Scenarios
Refractory ceramic fiber blanket is suitable for heating furnaces, annealing furnaces, glass kilns, incinerators, reactor insulation, high-temperature pipe coating, ships and other occasions.
