Description:

• SIRCA-14A uses the Ames Insulation Material (AIM-10) substrate with 0.16 g/cc density and is impregnated with silicone to produce a final density of approximately 0.224 g/cc. SIRCA-14A can withstand a higher heating rate than SIRCA-15F due to its pure silica substrate, but has lower mechanical properties than the SIRCA-15F. The material is best suited for high heating rate, low heat load and low mechanical load conditions.
