The mat of the three-way catalyst is widely used in vehicle exhaust emission systems to protect and seal the honeycomb ceramic carrier. The Dongheng three-way catalytic converter liner is applied in gasoline vehicles for TWC (three-way catalytic converter) and GPF (gasoline particulate trap); Applied in diesel vehicles for DOC (diesel oxidation catalyst), DPF (diesel particulate trap), and SCR (selective catalytic reduction).

Alumina fiber insulation mat is made of FP series fiber paper as the core material and encapsulated with thermoplastic film. It has excellent thermal insulation and buffering performance, mainly used for thermal protection between power lithium battery cells, which can effectively prevent battery cell thermal runaway and provide long-term safety guarantee for power batteries. It can also be applied in related fields such as energy storage.
