Shandong Huaci International Trade Co., Ltd. is one of the leading manufacturers and suppliers of high pure ceramic fiber blanket in China, featured by quality products and good service. Welcome to wholesale custom made high pure ceramic fiber blanket at competitive price from our factory. If you have any enquiry about quotation, please feel free to email us.
Product Description
Huaci High Purity Ceramic Fiber Blanket is engineered for industrial insulation systems where raw material purity, thermal stability and batch consistency are critical. It is manufactured from carefully selected high-purity alumina and silica raw materials, with a combined Al₂O₃ + SiO₂ content of at least 99%.
Compared with conventional ceramic fiber insulation, the high-purity formulation helps reduce the influence of unwanted impurities during prolonged thermal exposure. Through high-temperature melting, high-speed fiber spinning, multi-stage slag removal and double-sided needle punching, the blanket forms a uniform fiber structure with low heat storage, stable tensile strength and reduced heat transfer.

Product Advantages
99%+ High-Purity Fiber Composition
The key difference of this product lies in its controlled raw material purity. Al₂O₃ and SiO₂ account for at least 99% of the main composition, helping limit impurities that may negatively affect fiber stability during high-temperature service.
For industrial users, higher purity provides a more predictable insulation material for furnaces, thermal equipment and engineering systems operating under repeated heating cycles.
Stable Performance Under Continuous Heat
The blanket is designed for applications operating continuously at temperatures up to 1100°C. Its fiber structure maintains good dimensional and mechanical stability during repeated heating and cooling cycles, helping reduce premature deterioration in demanding thermal systems.
Low Thermal Conductivity for Heat-Loss Control
A fine and uniform fiber network minimizes heat transfer through the insulation layer. Thermal conductivity of 0.035–0.045 W/m·K at room temperature helps reduce heat loss from furnaces, pipelines and thermal processing equipment, supporting improved energy utilization over long operating cycles.
Needle-Punched Structure for Installation Reliability
Double-sided needle punching interlocks the fibers throughout the blanket instead of relying on chemical binders. This improves structural integrity and allows the material to be cut, wrapped, folded and fitted around curved or irregular surfaces during installation.
Eco-friendly & Fully Compliant Safety
Free of asbestos, formaldehyde and any hazardous substances, this blanket achieves Class A non-combustible rating. It complies with EU environmental regulations and global industrial safety standards, fully qualifying for high-standard overseas engineering and government-approved projects.
Customization, Packaging & Supply
Huaci supports both standard and project-specific production. Thickness, density, width and roll length can be adjusted according to equipment geometry, installation method and insulation design.
Standard specifications can be prepared for regular industrial requirements, while non-standard dimensions are available for furnace linings, large pipeline systems and special engineering structures.
Export packaging can be configured according to shipment volume and transportation conditions, with moisture-resistant inner protection and reinforced outer packaging used to protect the blanket during storage, container loading and international transport.
Small trial quantities and larger project orders can both be supported according to production planning.
FAQ
Q: What makes a High Purity Ceramic Fiber Blanket different from a standard ceramic fiber blanket?
A: The main difference is raw material composition. This product uses high-purity alumina and silica with a combined content of at least 99%, providing more controlled chemical composition and reduced impurity content for demanding thermal applications.
Q: What is the maximum continuous operating temperature?
A: The classification temperature is 1260°C, while the recommended long-term working temperature is up to 1100°C.
Q: Can density and dimensions be customized?
A: Yes. Density, thickness, width and length can be adjusted according to furnace structure, pipeline dimensions and project insulation requirements.
Q: Can you provide batch inspection records?
A: Yes. Production batches can be traced through raw material inspection, process control and finished-product testing records. Relevant inspection documentation can be supplied according to project requirements.
Q: Is the material combustible?
A: No. The blanket is classified as Class A non-combustible and is designed for high-temperature insulation and fire-resistant applications.
