Ceramic fiber gasket
Description
Ceramic fiber paper is made from refractory alumina silicate fiber, which can be used in the field of high temperature insulation. Ceramic fiber paper has the advantage of resistance to high temperature, low thermal conductivity and corrosion resistance. It can be used for thermal insulation, sealing, electric insulation, sound absorption, filtration etc instead of asbestos products as a kind of advanced light refractory material.
Application
1. Industrial Insulating, Sealing and protecting materials.
2. Electric and thermal insulation materials for electric industry.
3. Insulation materials for instrument-equipment.
4. Insulating materials for motor industry.
5. Filling materials for expansion slot.
6. Insulating materials as the sinter resistant.
7. Sealing gasket for molten metal.
8. Fireproof materials.
