Maxfire Blankets (1800ºF – 2600ºF Spun Insulation Blanket)

Maxfire Ceramic Blanket Products are comprised of high-strength ceramic fibers spun from alumina-silica, mechanically needled and cross-locked through a unique forming process, to produce a resilient blanket with unexcelled handling strength and surface integrity. All Ceramic Blanket Products are completely inorganic and available in a variety of densities, thickness and temperature capabilities. Maxfire Ceramic Blanket Products offer excellent thermal and acoustical performance, high temperature stability, low heat storage, thermal shock resistance and are unaffected by water or oil, with thermal and physical properties restored upon drying.

Thermal Conductivity (k)

All heat flow calculations are based on a surfaccell namemissivity factor of 0.90, an ambient temperature of 80ºF, and zero wind velocity, unless otherwise stated. All thermal conductivity values have been measured in accordance with ASTM C 177. When comparing similar data, it is advisable to check the validity of all thermal conductivity values and ensure the resulting heat flow calculations are based on the same condition factors. Variations in any of these factors will result in significant differences in the calculatecell nameata.

Other Information

Combustibility – Rated noncombustible per ASTM E-136; BS476P4/DIN4102
Surface Burning Characteristics – Flame spread 0; Smoke developed 0, per ASTM E-84
