High Aluminum Ceramic Fiber Blanket is a premium-grade thermal insulation material designed for extreme high-temperature environments. Manufactured by Xintai Refractory using a high-content alumina-silica formula (Al₂O₃ ≥ 52%), this blanket delivers exceptional thermal stability, chemical resistance, and mechanical durability under continuous exposure to temperatures up to 1200°C.
With a classification temperature of 1360°C, it is ideal for applications requiring enhanced resistance to heat, slag erosion, and thermal cycling. This product is produced through a spun fiber process and reinforced by double needling for improved tensile strength and structural integrity.

Production Details of Our Ceramic Fiber Blanket
High Aluminum Ceramic Fiber Blanket is manufactured through Xintai Refractory’s advanced spun fiber production line, where high-purity alumina-silica is melted and spun into continuous fibers. The blankets are double-needled to enhance tensile strength and reduce fiber loss. After trimming and rolling, each product undergoes rigorous quality inspection.
Packing and Shipping Details
For packaging, each blanket is wrapped in protective PE plastic film and packed into woven bags or cartons. Palletized shipping is used for large orders, ensuring stability during transport. We offer OEM customization, including printed logos and special packaging options, and support global delivery via sea, air, or express.
Frequently Asked Questions (FAQ)
Q1: What is the advantage of high aluminum over standard ceramic blankets?
A1: High aluminum blankets contain ≥52% Al₂O₃, which improves resistance to heat, chemical attack, and slag corrosion. They are ideal for more demanding applications above 1100°C.
Q2: Can I use this blanket as lining for a furnace?
A2: Yes. It is commonly used as hot-face insulation in furnaces, kilns, and other thermal equipment exposed to continuous high temperatures.
Q3: Is the material safe and asbestos-free?
A3: Absolutely. All Xintai ceramic fiber blankets are asbestos-free, non-toxic, and safe for use in industrial environments.
Q4: Do you support sample testing before bulk purchase?
A4: Yes, we provide free samples for testing. You only need to cover the shipping or we can deduct it from your first order.
Q5: Can I customize the thickness and dimensions?
A5: Yes. We offer a variety of thicknesses (6–50 mm) and widths (typically 610 mm), and can customize sizes upon request.
