ALUMINO SILICATE CERAMIC BLANKETS - CFI S Blankets

PCFI ceramic fiber wool blankets are available in various roll thicknesses, widths, lengths, and densities. They are easily die-cut to different shapes for your application.

Produced through a spinning process, spun fibers have longer fiber lengths with tightly controlled diameters and low sediments that lead to higher tensile strength properties. Its well-distributed interwoven construction offers superior erosion resistance and pliability.

Ceramic Fiber Paper

CFI's ceramic fiber paper is constructed by forming a nonwoven matrix of alumino-silicate spun fibers. The randomly oriented ceramic fibers are held together by an organic binder system that quickly burns off. Ceramic fiber papers can easily be cut into lightweight, flexible sheets with uniform thickness and density. Excellent for use as refractory backup, fire protection, thermal insulation, and high-temperature gasket, separator, or parting agent.
