Refractory cotton

Refractory cotton

This product has a white color and has the ability of sound and electrical insulation, and it can be said that it has these two features due to the purity of this product.

Refractory cotton is made of silica and aluminum oxide. This product also has an extraordinary heat tolerance.

Thermal tolerance of this product includes:

Melting point: 1790 ° C
Maximum tolerable temperature: 1100 to 1430 degrees Celsius
Heat tolerance for high use: 1050 to 1350 degrees Celsius
Refractory cotton made from ceramic fibers includes resistance to chemical corrosion, oxidation and mechanical resistance to impact, tension, tear and abrasion.

The most prominent benefits of asbestos are:

It is used in various environments.
They have high ductility.
It weighs little.
Easy handling.
It is resistant to heat shock and has non-combustible properties.
In high heat, it has high security.
It has low thermal conductivity.
It has good resistance in environments with steam, oil, water and alkaline and acidic environments.
It has resistance to tearing, traction, impact and abrasion and has acceptable mechanical strength.
It has electrical insulation properties.
It has a high sound absorption property.
In addition to these advantages, this product has a thickness of 60 to 6 mm.

This white product has an approximate density of up to 500 kg per cubic meter.

The advantages of this cotton have led to its use in many other products. These products along with heat tolerance include:

Refractory paper: For heavy use, 1000 degrees Celsius and the maximum tolerable amount of this product is up to 1260 degrees Celsius.
Fiber ceramic rope: For this rope for high heat use up to 1175 degrees Celsius has been set.
Fiber ceramic fabric: withstands heat up to 1000 degrees Celsius.
Refractory board: Withstands temperatures from 1260 to 1430 degrees Celsius.
Refractory blankets: This product, like refractory board, has a heat tolerance of 1260 to 1430 degrees Celsius.
Each of the above products has a different heat tolerance and has advantages and applications that have made them very popular.

The most important applications of asbestos are:

Sealing parts with asymmetric geometric shapes
In the pad manufacturing industry
Construction of expansion joints
Sealing of boilers and heating furnaces
