Standard Ceramic Fiber Blanket is a lightweight, flexible refractory insulation material made from high-purity alumina-silica fibers through a spun process. With a classification temperature of 1260°C and service temperature up to 1050°C, it offers excellent thermal stability, low thermal conductivity, and superior resistance to thermal shock and chemical attack.
This blanket is white in color, odorless, and suitable for a wide range of high-temperature industrial applications including furnace lining, back-up insulation, and high-temperature sealing. It maintains its structural integrity under extreme conditions while providing excellent energy-saving performance.

Frequently Asked Questions (FAQ)
Q1: Is the product safe for direct human handling?
A1: Yes. Xintai’s ceramic fiber blankets are asbestos-free, non-toxic, and safe when handled with proper PPE (e.g., gloves and mask during installation).
Q2: Can I get a sample for testing?
A2: Absolutely. We provide free samples for quality and performance evaluation—shipping cost to be covered by the customer or deducted from the first order.
Q3: What is the difference between standard and high-purity ceramic blankets?
A3: The main differences lie in alumina content, impurity level, and service temperature. High-purity blankets offer better thermal performance and are suitable for more demanding conditions.
Q4: Can this blanket be used as backing insulation?
A4: Yes, Standard Ceramic Fiber Blanket is commonly used as a backing layer behind dense refractories or castables to improve thermal efficiency.
Q5: Do you support OEM orders?
A5: Yes, we offer OEM services including customized size, labeling, and packaging.
