Ceramic fiber products refer to the industrial products with the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat and mechanical vibration resistance made of ceramic fiber as raw material, which are specially used in various high temperature, high pressure and wear environments.

Ceramic fiber blanket, also known as aluminum silicate fiber blanket, is called ceramic fiber blanket because one of its main components is aluminum oxide, which is also the main component of porcelain. Ceramic fiber blanket is mainly divided into ceramic fiber jet blanket and ceramic fiber silk blanket. Ceramic fiber silk blanket is superior to ceramic fiber jet blanket in thermal insulation performance due to its long fiber length and low thermal conductivity. Most thermal insulation pipeline construction uses ceramic fiber silk blanket.
