Catalytic converter support mat description
We offer a variety of catalytic converter support mats that provide high value, cost effective solutions for mechanical support of honeycomb ceramic substrate used in catalytic converters.
Function of support mat
1. Fixation and protecting of honeycomb ceramic substrate.
2. Airproof and preventing exhaust gas leak.
3. Excellent insulation properties and avoiding overheating of the shell.
4. Sound insulation and exhaust systems noise reduction.
Existing product include
1. ntumescent support mat.
2. Non-intumescent support mat.
3. Edge seal support mat.
4. Multilayer composite support mat.
5. Graphite intumescent support mat.
Intumescent support mat description
Intumescent support mat contains the high temperature expansion of vermiculite. It is used for most conventional catalytic converter, widely used in gasoline and diesel systems mounting designs and applications.

Non-intumescent support mat description
Non-intumescent support mat do not contain the high temperature expansion of vermiculite. It is used for gasoline system applications, especially ultra-thin wall ceramic substrate, and can also be used as the edge sealing of the expansion cushion.
Technical data
Edge seal support mat description
Edge seal support mat comprises one or two narrow strips of non-intumescent support mat on one or both sides of a wide strip of intumescent mat. It is used for close coupled and manifold catalytic converter, wide oval ceramic substrate and racetrack ceramic substrate.
Model Number: KT100/200
Multilayer composite support mat description
Multilayer composite support mat is normally comprises a layer of intumescent support mat and a layer of non-intumescent support mat. It is used for gasoline system applications, especially ultra-thin wall ceramic substrate.
Technical data
Graphite intumescent support mat description
Graphite intumescent support mat contains the high temperature expansion of vermiculite and the expandable graphite. It is used for gasoline as well as diesel systems mounting designs and applications, especially diesel particle filters.
