Description Refractory ceramic fiber blanket LYTX thermal insulation up to 1260°C mullite-silica composition

Roll material of high temperature thermal insulation ceramic fiber. LYTX refractory wool is an excellent alternative to standard thermal insulation products. Combines high thermal stability and low thermal conductivity. Roll refractories for lining are the most versatile, flexible and resilient material, pliable in cutting and installation. In the process of high - temperature operation, it does not emit toxic substances, does not corrode in chemical environments, and perfectly repels moisture.

Type: white fireproof mats, assembled in rolls and completely ready for use.

Refractory blanket (mat) LYTX is an indispensable material in industries related to high temperatures, heat treatment, thermal insulation, as well as in the production of furnaces and boilers of various types. They are made of mullite - silica fibers, which are produced by melting pure aluminum and silicon oxides in an electric furnace. For use at high temperatures, zirconium or chromium oxides are added to the refractory mats.

Properties and benefits:

• the material is non - combustible;
• does not contain asbestos;
• thermal resistance;
• chemical resistance
• low thermal conductivity;
• high tensile strength;
• high elasticity and flexibility;
• excellent sound absorption;
• reduction of metal consumption of the lining structure;
• manufacturability and ease of installation.
