ceramic fiber paper
ceramic fiber paper


1.The ceramic fiber paper is manufactured by refractory fiber with high purity which is used in high-temperature insulating fields.
2.The advance manufacturing technology makes the distribution of fiber be very even and the paper’s thickness and storage can also be controlled strictly.
3.Ceramic fiber paper is made of refractory ceramic fiber with a little bond which is selected scientifically and controlled strictly.
4.The bond will be completely burnt during the use. The product does not contain asbestos and is perfect material for sealing and insulating.
