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).

Three way catalyst mat: Alumina short fibers are mainly used to make the sealing mat for the outer layer of the three-way catalyst, which plays a role in fixing, sealing, vibration reduction, and sound insulation of the catalyst honeycomb carrier. |

Thermal insulation material: Alumina short fiber, due to its excellent high temperature resistance and thermal insulation performance, can be applied to various insulation systems in automobiles, such as exhaust pipes, brake discs, and racing pedals, giving it a more stable friction coefficient, good braking effect, and longer service life. |

Aluminum based composite materials reinforced with alumina fibers can be used for high load mechanical parts, high-temperature and high-speed rotating parts, as well as high-performance components that require lightweight design, such as automotive connecting rods, transmission shafts, brake pads, diesel engine piston ring shoulders, cylinder liners, cylinder heads, valve groups, connecting rods, and piston pins. Compared with aluminum alloys that do not use alumina fiber reinforcement, the tensile strength of the reinforced components increases by 400% at a working temperature of 300 ℃, and the maximum working temperature can be increased to 500 ℃. |
