THERMAL RATING
LI-2200 is a ceramic tile thermal protection system by Lockheed Missiles & Space Company. Rated to 1,260°C. Status: Retired (Shuttle).
ABOUT LI-2200
LI-2200 is a higher-density variant of the Shuttle’s silica tile system, offering improved strength and durability compared to LI-900. It was used in areas requiring greater structural integrity while maintaining good thermal protection. The tiles were bonded to the Shuttle’s aluminum airframe with RTV adhesive and strain isolation pads.
