High Temperature Refractory

Refractory materials are strong at high temperatures, resistant to thermal shock, chemically inert, and have low thermal conductivities and coefficients of expansion. High temperature refractory insulation products are used when the material must withstand extremely high temperatures. Refractories must be chosen according to the conditions they will face.

Refractory blankets are used for a variety of high temperature applications. These may include but are not limited to: Furnace, Kiln, & Oven Linings; Boiler & Turbine Insulation; Incinerator Linings; High Temperature Gaskets a& Seals; Duct, Stack, & Flue Linings; and Fire Protection.

 

Fiberfrax® alumino-silicate fibers exhibit high temperature stability for continuous use at temperatures up to 1430°C (2600°F). All Fiberfrax fiber products are characterized by, low thermal conductivity, low heat storage, excellent thermal shock resistance, light weight, and superior corrosion resistance.

 

Kaowool® by Thermal Ceramics is the original asbestos replacement material invented by Babcock and Wilcox. The great advantage of Kaowool® over other refractories is its very low density and ease of handling. The density of Kaowool® is approximately the same as dense fiber glass blanket. This ease of handling offsets the cost difference as compared to castable or refractory brick making Kaowool® a solid insulation value.

 

The Thermal Ceramics Superwool® family of products offers a versatile alternative to traditional insulation solutions for commercial, industrial, and transportation applications. Superwool® products are special alkaline earth composition fibers that have been uniquely engineered to offer advantages in high temperature insulation applications with low thermal conductivity, low bio-persistence, low linear shrinkage up to their use limit.
