SEALING AND INSULATION
ACF™ CERAMIC FIBER PRODUCTS – For High Temperature Insulation and Sealing Applications
Aluminosilicate Ceramic Fiber Products
ACF(Aluminosilicate Ceramic Fiber) is manufacturered from high-purity aluminosilicate material for use in applications up to 2300 °F (1260 °C). Its main composition is a kind of inorganic mineral which has a long fiber crystal. This kind of mineral is very stable in high temperature and not harmful to human health. Therefore, Aluminosilicate Ceramic Fiber is being used as an ideal substitute of asbestos in insulating and sealing applications.
By spinning and weaving ceramic fiber through a special technology process, Ceramic Fiber can be made into Ceramic Fiber Yarn, Ceramic Fiber Cloth, Ceramic Fiber Rope(Packing), Ceramic Fiber Paper, Ceramic Fiber Blanket, Ceramic Fiber Board, and so forth.
Ceramic Fiber products have the properties of light weight, good heat insulation, non-poisonous etc. They are resistant to high temperature and thermal shock, and also resistant to attack from most corrosive agents. Exceptions are hydrofluoric and phosphoric acids, and concentrated alkalis.
Ceramic Fiber products can be used as refractory materials for heat insulation, or fluid sealing. They can be applied in furnaces, valves, pipelines and many other facilities. The application fields may include metallurgical industry, chemical industry, mechanical industry, petro-industry, marine industry, etc.

Material Safety Information:
Ceramic fiber may cause irritation to skin and eyes. Wearing protective clothing and gloves is recommended for handling. May be harmful if inhaled depending on duration and level of exposure. Generically, ceramic fiber is identified by IARC as a cristobalite at high temperature above 1800 degree F. Keep airborne fiber exposure at the lowest level. Avoid unnecessary handling after the material has been used at high temperature.
For more information, please refer to our Material Safety Data Sheet (MSDS).
