Firewall Barriers & Engine Nacelles
Ultra-high-temperature, flame-resistant compounds engineered to insulate and safeguard critical power plant enclaves and engine nacelles. Formulated with advanced silicone and refractory technologies, these sealants form an impenetrable thermal barrier capable of withstanding direct flame exposure up to 1,093°C (2,000°F) for at least 15 minutes, preventing fire, toxic gases, and fuel vapors from penetrating into neighboring structural zones.
