Product Description

Ceramic fiber board, adopting corresponding spun fiber  as the raw materials ,are produced by vacuum formed technology,
NR ceramic fiber board doesn't only pssess the same function of fiber but also has hard texture excellent toughness and intensity and excellent fiber resistant and heat preservation.

NRCL supply ceramic fiber board which 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 .

Ceramic Fiber Board Characters
Low heat storage -  Wide bulk density, 250-400kg/m3  -Variety grades, the boards can be classified by temperature to be 1100ºC-1430ºC Low thermal conductivity and shrinkage  -  Excellent resistance against chemical attack Easy to machined, cut and install

Ceramic Fiber Board Product Applications
Petrochemical process heater refractory fiber lining 
Heat treating furnace or intermittent (shuttle) kiln hot face lining 
General furnace backup insulation 
Heat seals for kiln car or furnace door 
Electrical insulator 
High temperature acoustic 
Fire protection
