Ceramic Fiber Blanket for Kiln and Furnace Insulation
Description
Ceramic fiber blanket is a needled refractory insulation material widely used for kiln lining, furnace backup insulation, high-temperature pipe wrapping and thermal sealing. It is made from high-purity ceramic fibers and processed by double-sided needling, giving the blanket excellent flexibility, low thermal conductivity, thermal shock resistance and easy installation performance.
It is available in multiple temperature grades, densities and thicknesses to meet different industrial insulation requirements. Ceramic fiber blanket is commonly used in steel, ceramics, petrochemical, heat treatment and power generation industries where lightweight high-temperature insulation is required.

Productive Process
Ceramic fiber blanket is produced from selected high-purity raw materials that are melted at high temperature and converted into fibers through a fiberizing process. The loose ceramic fibers are then collected and formed into a continuous blanket structure.
After fiber formation, the blanket is processed by double-sided needling to improve tensile strength, flexibility and structural stability. This needling process helps the blanket maintain uniform thickness and good handling performance during installation.
After needling, the product is trimmed, slit and cut into standard sizes according to required thickness, width and roll length. Each batch is inspected for density, thickness, dimensional accuracy and appearance before packing, ensuring stable quality for kiln, furnace and high-temperature insulation applications.
Packing And Shipping
Ceramic fiber blanket is usually packed in moisture-proof plastic bags or woven bags to keep the rolls clean, dry and protected during storage and transportation. Standard export packing can be provided for sea, air or land shipment according to customer requirements.
Each roll is clearly labeled with product name, temperature grade, density, thickness, size and batch information for easy identification and warehouse management. Pallet packing, carton protection and OEM labels are available if required.
We can also provide customized packing solutions based on loading method, container space and project delivery requirements to help customers improve transportation efficiency and protect the product during long-distance shipment.
