AVSil® Preshrunk Silica Needled Insulation is manufactured from amorphous silica fibers and is typically used in a wide range of critical, high temperature aerospace, automotive, and industrial applications. AVSil® Preshrunk Silica Needled Insulation is designed to withstand temperatures of up to 2000°F (1093°C), and is comprised of non-respirable, 9-micron filament fibers that are mechanically bonded, containing no added resins or adhesives.

The nominal density of AVSil® Preshrunk Silica Needled Insulation is 8 lb./ft³. The areal shrinkage is less than 4.0 percent. AVSil® Preshrunk Silica Needled Insulation contains no shot and is environmentally friendly since it contains no harmful refractory ceramic fibers (RCF). It can easily be fabricated into textile parts due to handling and strength properties.
