Endothermic Mat
1-4hours fire Protection wrapping for Steel, Cables tray& Conduit
Endothermic Mat is a flexible, high-performance fire protection solution engineered to absorb heat and release chemically-bound water when exposed to high temperatures. This reaction cools protected surfaces and delays heat transfer, giving critical infrastructure additional time during fire events. With its lightweight yet durable design, ET-MAT is easy to cut, shape, and install around complex geometries, offering versatile protection for both new installations and retrofit applications.
Endothermic fire protection mat safeguards cables, steel, and equipment in power plants, substations, and energy infrastructure.

FAQ
How does Endothermic Mat protect against fire?
When exposed to extreme heat, Endothermic mat releases water vapor that cools protected surfaces, delaying heat transfer and extending fire resistance.
Under what conditions should an endothermic mat be selected instead of a conventional ceramic fiber blanket?
Endothermic mats feature a unique heat-absorption mechanism that slows down the temperature rise inside cable trays. This allows critical cables—such as communication cables and power cables that must remain operational during emergency conditions—to function for a longer period of time.
Compared with conventional ceramic fiber blankets, endothermic mats provide longer fire resistance performance and are suitable for applications requiring 1 to 4 hours of fire protection.
They can be tested and qualified according to standards such as ASTM E119 and UL 1709.
What are the main applications of endothermic mats?
Endothermic mats are mainly used in high-risk and critical facilities, including:
1）Wrapping of cable trays and cable conduits in critical locations such as nuclear power plants, thermal power plants, data centers， tunnel and subway
2） Fire protection of structural steel in environments such as chemical plants and offshore platforms，Energy storage systems with high fire protection requirements
Does the release of water from an endothermic mat under heat affect electrical insulation?
Endothermic mats release chemically bound water only at elevated temperatures during fire exposure.
In addition, the amount of released water is relatively small and is typically carried away by flames and hot gases, so it does not adversely affect the electrical insulation performance of the system.
Can the endothermic mat be supplied with a foil facing?
Yes. Endothermic mats can be supplied in different surface configurations, including:
Without foil facing
With aluminum foil
With stainless steel foil
The metal foil thickness can be selected in the range of 0.04–3 mm, depending on the application environment and protection requirements.
Can Endothermic mat be installed on complex shapes?
Yes. Its flexible structure allows easy installation around corners, bends, and irregular components. It is suitable to wrap the control box, conduit and structrual steel etc…
