Polycrystalline mullite fibers, with a service temperature of 1800 degrees, are 200 to 300 degrees hotter than glass fibers.It can
be widely used in metallurgy, machinery, electronics, ceramics, chemical industry, aerospace and other high temperature industrial
furnaces and other thermal insulation equipment, lining insulation materials.In order to save energy and increase efficiency, lengthen furnace life, lengthen furnace life to improve the working environment.
