Ceramic Fiber Board

NR ceramic fiber boards, adopting corresponding spun fiber  (COM.ST.HA.HP.HZ)   as the  material ,are produced by vacuum formed technology.  The ceramic fiber board does not only possess the same function of fiber but also has hard texture excellent toughness and intensity and excellent fiber resistant 

and heat preservation. NR ceramic fiber board are made of different refractory fiber bulks with excellent chemical stability, organic and inorganic bond by wet method and vacuum forming processing which is applicable to many kinds of industries .The fiber board with a characteristics of hard, flexible, excellent strength and resistance against corrosion.
