WH ceramic fiber board is made by vacuum forming corresponding grade ceramic fiber cotton with inorganic binder and a small amount of organic binder. The highest temperature resistance level is 1800 ° C. In some equipment, the small amount of organic binder in the product will smoke when burned, which is a normal phenomenon and will quickly dissipate. Inorganic board: According to customer needs, all products are formed using inorganic binders, and no organic volatiles are produced during use; Hardened board: The product can be surface hardened or fully hardened according to customer needs, resulting in better strength; Hydrophobic board: The product can be surface waterproofed according to customer needs, with a hydrophobicity rate greater than 98%, suitable for certain special parts.
