Aluminum Silicate Fiber Board
Low heat capacity, low thermal conductivity, long service life
Application
Widely used for thermal insulation of heating aggregates
Description
Aluminosilicate boards are produced by melting selected fireclay in electric furnaces at temperatures exceeding 2000°C, followed by mechanical fiber spraying, uniform addition of binders, oil-repellent and hydrophobic agents, and thermal curing.Specifications
