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
