PRODUCT DESCRIPTION：YONAI Silica Insulation Brick
YONAI provides world-class silica insulating bricks.
YONAI Silica Insulating Bricks are made of crystal silica by adding compound flammable substances. The product can well preserve heat while working under high temperature. The products are the major energy saving materials among blasting furnace refractories. Our silica insulating bricks can reduce 70%-90% energy and heat radiation loss.
Major Application:
Widely used as key material in heat insulating layer (can not meet molten slag and temperature under 1500℃) of various high temperature furnaces and kilns.
