With high resistance to thermal shock, fire blanket acts as a thermal barrier and is capable to endure the stresses caused by rapid temperature changes without undergoing significant physical damage, such as cracking, breaking, or losing structural integrity.

Each layer provides a specific function: silica fabric for direct high-heat exposure and fiberglass needle mat for additional insulation and protection.

Very important leverage of ULTRA+ blanket is the high thermal resistance and fire-retardant properties to contain and suppress battery fires, which can be particularly challenging due to the high energy content and volatile nature of lithium-ion batteries.
