Silica needled mats are a heat resistant material which can be used over long periods without loss of properties and without melting and vaporising at temperatures of up to 1832oF (1000ºC). The mats also have low thermal conductivity, are inert to the majority of chemical reagents, resistant to organic and mineral acids (except hydrofluoric and phosphoric), weak alkali, water and high-pressure steam.

Application: High-silica needled mats are mainly used in metallurgy, automotive industry, electro- and chemical industries, which require thermal resistance of up to 1832oF+ (1000ºC+).
