Needled High Silica Mat

High Silica Mat is a high performance nonwoven mat with a SiO2 content of 96% to 99%. Due to its outstanding low heat conductivity it used for thermal insulation and heat protection where severe temperature conditions exist. Until quite recently these materials were used only in aircraft and aerospace industries, but now they are used in various branches of industry, where heat resistant materials are required.

It will not burn, rot or deteriorate. It is inert to the majority of chemical reagents, resistant to organic and mineral acids (except hydrofluoric and phosphoric), weak alkali, water and high-pressure steam. High electrical insulation property at elevated temperature makes it ideal for many applications.

High silica needled mat maintains its excellent properties after long exposure to temperatures as high as 1800°F, and short-time exposure up to 2300°F.
