Definitions for "Thermal Barrier"
Keywords:  foam, delay, icynene, combustors, slow
Material used in conjunction with polyurethane foam that is designed to inhibit the rise in temperature of the foam during a fire in order to delay the foam’s involvement in the fire. Time ratings for thermal barriers should exceed 15 minutes.
A material applied over IcyneneÔ Insulation designed to slow the temperature rise of the foam during a fire situation and delay its involvement in the fire.
Thermal Barrier: A thermal spray coating used to reduce the rate of heat transfer to allow the components to operate at a higher temperature. Coatings normally associated with combustors for the Gas Turbine
A boundary to heat flow. i.e. insulation
a limit to high speed flight imposed by aerodynamic heating
