Ceramic Fiber Board

  • Ceramic fiber board is made by wet vacuum forming process or dry manufacturing process.
  • Detail

Production Process:

Ceramic fiber board is made by wet vacuum forming process or dry manufacturing process.

The strength of this kind of product is higher than that of fiber blanket and vacuum forming felt, so it is suitable for the high temperature field with steel strength requirement.


Product Characteristics:

Low thermal conductivity, low heat density

Excellent thermal stability and thermal shock resistance

High compressive strength and good toughness


Product Application:

Thermal insulation of high temperature equipment

Industrial kiln backing material, masonry insulation layer

Heat insulating material heating device

Thermal insulation and fire-retardant materials for metallurgy, petrochemical, glass, ceramics, non-ferrous metals and other industries

Kiln lining, kiln car, door baffle and temperature partition board of high temperature kiln

Heat insulation, fire prevention, sound insulation and insulation in aerospace and shipbuilding industry
