What is Isowool Ceramic Fiber?

Isowool is a ceramic fiber made from the purest of raw materials, which are electromelted, air-blown at high speed and fiberized. Light in weight and soft to the touch, Isowool possesses excellent refractory and insulating properties. It sees extensive applications in such key industries as steel, nonferrous, petrochemical and ceramic. Not only that, but it finds wide use also for seals, for filters , for filters and as reinforcing fiber of various composites.

Type & Use

Ceramic fiber varieties are: ordinary aluminum silicate fiber, aluminum silicate aluminum fiber, aluminum silicate fiber, polycrystalline alumina fiber and polycrystalline mullite fiber. In recent years, foreign countries have successfully developed some new varieties of ceramic fiber, such as: ceramic fiber. Ceramic fiber products are mainly: ceramic fiber cotton, ceramic fiber felt, ceramic fiber blanket, ceramic fiber module, ceramic fiber paper, ceramic fiber cloth, ceramic fiber belt, ceramic fiber rope and so on.

Ceramic Fiber Blanket (Fiber Module)

The use of self-melting, even the melting of the production process made of long silk spinning, the double-sided acupuncture fibers made of intertwined, can be directly as a hot flame, set fire Heat, insulation in one, in the neutral, oxidizing and partial reductive atmosphere in the long-term use, can still maintain a good strength, toughness. The fibrous module made of this fiber blanket does not contain bonding agent, good thermal stability, widely used in petrochemical, metallurgical, power and other heat insulation field.

Ceramic Fiber Board

Ceramic fiber and binder, additives, through the pulp, molding, curing, drying and other processes made. Ceramic fiber board is flexible, easy to cut, high strength, is a low thermal conductivity, low heat storage of new energy-saving environmental protection products, widely used in a variety of heating equipment, the top of the wall, the top part of the backing, is a heavy refractory.

Ceramic Fiber Cloth

mainly used in fire doors, industrial furnace insulation, high temperature pipes and containers of insulation.

Ceramic Fiber Rope

Mainly used in a variety of industrial furnace expansion joints, high temperature pipe winding insulation, steel structure, such as the junction of insulation.
