Ceramic fiber is a lightweight, high-temperature insulation material composed primarily of alumina-silica. Manufactured through a melting and fiberizing process, it creates a wool-like product with exceptional thermal stability and low thermal conductivity. This engineered material is designed to withstand extreme temperatures where traditional insulation fails, making it a cornerstone of thermal management in demanding industrial applications. At Kaxite Seals, we specialize in providing high-performance ceramic fiber solutions that meet rigorous standards for efficiency and durability.
The superior properties of ceramic fiber translate into tangible benefits for operations. Its low heat storage allows for rapid cycling of furnaces and kilns, significantly improving energy efficiency and reducing operational costs. The material's flexibility and resilience make it easy to install around complex geometries, ensuring complete thermal protection. Furthermore, its resistance to thermal shock prevents cracking and degradation during rapid temperature changes, extending service life. Kaxite Seals' products are engineered to maximize these advantages, delivering consistent performance and reliability.
Kaxite Seals offers a comprehensive range of ceramic fiber products, each designed for specific thermal and physical requirements. Below are detailed parameters for our standard blanket and board products.

The versatility of Kaxite Seals ceramic fiber makes it suitable for a vast array of high-temperature environments. Its primary function is to provide efficient thermal insulation, conserve energy, and protect personnel and equipment.
Q: What is the maximum temperature ceramic fiber can withstand?
A: The maximum service temperature varies by product grade. Standard ceramic fiber blankets from Kaxite Seals are rated for continuous use up to 1260°C (2300°F). Our high-purity grades handle up to 1400°C (2552°F), and zirconia-enhanced grades can withstand temperatures up to 1600°C (2912°F) in intermittent applications. It is crucial to select a grade with a temperature rating exceeding your operating temperature for safety and longevity.
Q: Is ceramic fiber safe to handle? What precautions are necessary?
A: While the finished products are generally stable, ceramic fiber in its raw, unbonded form is considered a nuisance dust. During handling, cutting, or installation, it is recommended to wear appropriate Personal Protective Equipment (PPE) including gloves, safety glasses, and a dust mask (NIOSH N95 or equivalent) to prevent temporary skin or respiratory irritation. Kaxite Seals also offers pre-cut kits and bonded or coated products that significantly reduce fiber dust during installation.
Q: How does ceramic fiber compare to traditional refractory bricks?
A: Ceramic fiber offers several key advantages over dense refractory bricks. It is significantly lighter (reducing structural load), has much lower thermal conductivity (improving energy efficiency by 20-40%), and possesses superior thermal shock resistance. While bricks have higher mechanical strength, ceramic fiber modules and boards from Kaxite Seals provide faster installation, lower heat storage for faster furnace cycling, and overall reduced lifecycle cost in most high-temperature applications.
Q: Can ceramic fiber get wet? What happens if it does?
A: Ceramic fiber is hygroscopic and will absorb moisture if exposed to water. While getting wet does not permanently destroy its insulating properties, it can cause the material to become soggy, lose its resilience temporarily, and may lead to shrinkage when first heated as the water evaporates. It is best to store products in a dry place and install them in dry conditions. If wet, the material should be allowed to dry thoroughly before being heated to operating temperature.
Q: What forms does ceramic fiber come in?
A: Kaxite Seals supplies ceramic fiber in multiple forms to suit different application needs. These include:
Q: How do I select the right density for my application?
A: Density selection depends on the required thermal performance, mechanical strength, and installation method. Lower densities (64-96 kg/m³) are excellent for back-up insulation and applications where weight is critical. Medium densities (96-128 kg/m³) offer a good balance of insulation value and durability for hot face linings. Higher densities (128 kg/m³ and above, or in board form) provide greater resistance to erosion, gas velocity, and physical abuse in high-wear areas. Kaxite Seals' technical team can provide specific guidance based on your furnace atmosphere, temperature profile, and process requirements.
