Our ceramic fiber insulation board is a high-efficiency thermal insulation material, mainly used in scenarios that require precise temperature control. It takes high-purity aluminum silicate fiber as the core raw material, processed by compression forming technology. It has low heat storage capacity, so equipment can heat up and cool down quickly-saving a lot of time in actual production. The ceramic fiber insulation board's structure helps reduce heat transfer, which is why it's commonly used in electronic component sintering furnaces, laboratory high-temperature equipment, and industrial pipelines that need stable, precise temperature control.

FAQ
Q: How does it compare to ceramic fiber blanket in insulation effect?
A: It has 15% better insulation than ceramic fiber blanket, thanks to its higher density. It's more suitable for occasions where heat loss needs strict control.
Q: Can it be used in vacuum environments?
A: Yes, it has a low outgassing rate, so it's applicable to vacuum high-temperature furnaces and even some aerospace-related equipment.
Q: Does it absorb moisture?
A: Its water absorption is low-no more than 5% after 24 hours of immersion. And after drying, its insulation and other performances can be fully restored, so it can be used normally again.
