Ronghua Refractory offers free samples for customers to check the quantity whether meets their requirements. This is one of the samples shipped to a customer.
High-quality Production of Ronghua Ceramic Blanket
Good Raw Materials: Its main components are kaolin, alumina, and silica. These raw materials give the finished ceramic fiber blanket excellent thermal stability and high-temperature resistance.
Good Process: This ceramic fiber product is an insulation material made of ceramic fibers through needling and other processes. The needling process interlaces the ceramic fibers to form a strong network structure. It can improve the performance of the refractory blanket, such as strength, wear resistance, thermal insulation, and so on.
Advanced Manufacturing Equipment: Upgraded real thorn carpet production line.
Patents and Technology: Multiple patented ceramic fiber production technologies.

Characters of Ceramic Fiber Insulation Blanket
1. Excellent thermal insulation: Ceramic fiber blankets have low thermal conductivity, effectively reduce heat transfer. Ideal for furnaces, kilns, and industrial ovens.
2. High-temperature resistance: The blankets can withstand extremely high temperatures, up to 1430°C or even higher.
3. Low Thermal Conductivity: The thermal conductivity of Kerui ceramic fiber blankets is low. The thermal conductivity is between 0.09-0.76 W/mK at 400-1000°C.
4. Strong Mechanical Properties: Ceramic blanket insulation has strong mechanical properties, like tensile strength, wear resistance, tear strength, elasticity.
5. Chemical Corrosion Resistance: High heat insulation blankets have good chemical stability. They resist most acidic and alkaline chemical erosion.
6. Noise Reduction: Blanket ceramic fibers have a porous structure, high density and light weight. Effectively absorb sound waves and block sound transmission.
