JIUQIANG ceramic fiber boards are rigid products made from ceramic fiberr which is vacuum formed with organic and inorganic binders, with or without mineral fillers. These are manufactured over a wide range of grades densities and hardnesses.
The boards are featured with high temperature stability, low thermal conductivity, even density, and excellent resistance against thermal shock and chemical attack. They can be used as individual component of furnace linings or as hard hot face layer as backup insulation.
