Alumina continuous fiber can be used for hypersonic aircraft, antenna covers, and radar transmission covers. Using alumina continuous fiber as a new generation material with higher temperature requirements has become a trend. European and American countries have already applied this material to space shuttles, interstellar spacecraft, and weapon equipment, which can play a good role in temperature resistance and thermal insulation.

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 short fibers can be used at temperatures ranging from 1200 ℃ to 1800 ℃. Their fiber products, such as fiber blankets, felts, paper, modules, and shaped parts, have low density and heat capacity, low thermal conductivity, and good thermal shock resistance. They can also be directly used as insulation filling materials for high-temperature kilns, such as furnace sidewalls, roofs, and doors, and as insulation seals for high-temperature components.

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.
