what is Ceramic Fiber Bulk?
Ceramic fiber bulk is a high-performance thermal insulation material, mainly made of ceramic components such as aluminosilicate and zirconium, with excellent high temperature resistance, and can withstand temperatures as high as 1260°C to 1800°C. It is lightweight, linh hoạt, easy to handle and install, and is suitable for thermal insulation and heat preservation in high temperature environments such as industrial furnaces and boilers.
Ngoài ra, ceramic fiber bulk has good chemical corrosion resistance, can be used under harsh conditions, and meets environmental standards, safe and harmless. Due to its superior performance, it is widely used in construction, metallurgy, aviation and other fields.

What is the difference between ceramic fiber bulk and ceramic fiber blanket？
Although both Ceramic Fiber Bulk and Ceramic Fiber Blanket are ceramic fiber materials, they have significant differences in structure and application. Ceramic fiber bulk materials are usually light and fluffy particles, mainly used to fill the interior of industrial furnaces or boilers to provide excellent thermal insulation performance. Its advantages are that it can adapt to complex shapes, improve thermal efficiency, and help reduce heat loss.
Ngược lại, ceramic fiber blankets are made of ceramic fibers tightly pressed in a blanket form. It has a dense texture and usually has excellent toughness and wear resistance. It is suitable for occasions that require high-temperature insulation and fire protection, such as high-temperature furnace walls, incinerators and welding processes. Ceramic fiber blankets can provide better mechanical strength and tear resistance when applied, and are suitable for withstanding high temperatures for a long time.
The choice of which material should be reasonably evaluated based on the specific application requirements.
