Description of Ceramic Paper Insulation

Ceramic refractory paper is a ceramic fiber product produced using a wet process combining ceramic fiber cotton and additives. We offer standard density paper and high-density paper. They are also known as soft fiber paper and semi-hard refractory paper. The softness, elasticity, and tensile strength of ceramic fiber soft paper are stronger than semi-hard paper.


Advantages of Ceramic Fiber Paper Roll

  • High-temperature resistance: Ceramic paper insulation can be used at high temperatures ranging from 1220 to 1350 degrees Celsius.
  • Thermal insulation performance: This type of product has the characteristics of low thermal conductivity and low heat capacity. Its thermal conductivity ranges from 0.06 to 0.43 W/(m·K) between 200-1000ºC. It can effectively reduce heat loss in equipment.
  • Excellent electrical insulation performance: Its fiber structure and chemical composition give it good electrical insulation effects. This feature makes it an ideal electrical insulation material in high-pressure environments.
  • Excellent machinability: This lightweight product can be processed into shapes and thicknesses as required for specific applications. It is very convenient for construction.
  • High flexibility: Ceramic fiber insulation paper is soft and has high tensile strength. It exhibits good abrasion resistance in high-temperature applications.
  • Good sound absorption effect: The multi-cellular structure, open fibers, and good damping characteristics make this product have excellent sound absorption effects. It can be used for noise control.
