On the Space Shuttle, short duration exposure to temperatures exceeding 1200°F may be encountered. In aircraft engine applications, continuous use temperatures range between 300-600°F. The MA-25S material has been FAA certified for fire proof protection of fan thrust reversers per FAR Part 25.1181a and FAA Advisory Circular AC 20-135.
The material is a filled elastomeric silicone which is available in either a sprayable or trowelable form.
