Ceramic Fiber Blankets
Introduction
The NC ceramic fiber blanket is made of special ceramic fiber through double needle-punching processing. The double needle-punching techniques improve the degree of fiber intertexture, and the performance of delamination resistance as well as tensile strength. The blanket does not contain any bonding agent and with the characteristics of stable chemical performance, resistance to most erosion of the chemicals. The physical properties, like refractoriness and insulation, remain the same when meeting with oil, water, or steam.
Characteristics
Excellent chemical stability, nonflammable; Low thermal conductivity and good insulation; Good tensile strength and springiness; Excellent performance of soundproofing and resistance to heat-shock.
Application
Internal and external lining for industry furnace; Internal and external insulation for pipeline; Insulation for home application, nuclear power, and aerospace; Joint sealing and filling insulation; Expansion seals/pipe coverings.

A furnace lining rarely fails because the furnace reached an impossible temperature. It usually fails because the refractory material was selected for the wrong mix of heat, chemistry, load, and thermal cycling. The symptoms are familiar: spalling on the hot face, open joints, corroded anchors, and a shell that quietly consumes gas or electricity for months. Short answer: choose furnace refractory material by failure mode first, temperature second, and price third. Ceramic fiber and lightweigh...
