Continuous ceramic fiber is a Boron-free, Alumina-Silica poly crystal made up of several thousand fine filaments that gives it excellent flexibility and allows it to be readily transformed into various textile forms such as thread, rope, woven cloth, tape and braided sleeve without the aid of any other organic fiber.
Continuous ceramic fiber has properties such as high tensile strength and modulus, excellent thermal resistance and outstanding electrical insulation. It has a wide range of applications in high temperature operating environment. 


• Superior flexibility
• Does not absorb moisture
• Excellent thermal resistance
• Good thermal insulation properties
• Good electrical insulation properties

• Ceramic fiber felt
Ceramic fiber felt is produced from chopped long fibers containing alumina (72%) and silica (28%) providing overwhelmingly higher heat resistance as compared to felt containing heat-resistant organic fibers. It also has advantage of being more compact for air flow resistance. Ceramic felt less resistance to air flow can also be provided by parallel orientation of the fibers.

 It has excellent heat resistance property. It can endure  continuous use at temperatures as high as  1,260°C. 

 It has excellent resistance to chemicals, especially against  corrosive acids. 

 It possesses good electrical insulation property, low thermal  conductivity and low electric loss even at  elevated  temperatures.

 Its extra-long fibers help it retain its shape and mechanical strength even after heat  processing or after bending. 

 It possesses adequate elasticity and shock absorbing capacity making it suitable as a  buffer or cushion material for high  temperature applications.


It has wide range of applications from use as insulation material in domestic heating appliances to various industrial applications such as gasket/packing material for high temperature parts, filling material to allow brick expansion, packing material for thermocouple protection tubes protective material for induction furnace coil and as packing material inside boilers, driers and engines. Chemical resistance, erosion resistance as well as heat resistance makes it ideally suitable for filtering and absorbing gases or liquids in high temperature environment. Due to its shock absorbing characteristics it can be used as a cushion material for filter inside chimney at plants such as thermal power station or garbage processing plants. It is especially suitable for applications that need thin structure high temperature insulation material.


Ceramic fiber paper is made of extremely fine inorganic fibers of alumina and Silica with a very small amount of organic binder. It is an inert material with excellent heat resistance and heat insulation properties. It can be formed into thin or thick structure paper sheets with thickness ranging from 1~4mm.
