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.
