Ceramic Fiber

Ceramic fiber products withstand extreme temperatures, and demonstrate an excellent ability to resist chemical attack. They are flexible, light-weight thermal and acoustical insulators with low thermal conductivities. Low bio-persistency alkaline earth silicates share similar properties with ceramic fibers while also allowing users to remain compliant with RCF substitution requirements.

We fabricate and distribute a comprehensive selection ceramic fiber and alkaline earth silicate products from Thermal Ceramics, Fiberfrax, and Lytherm.
