Product Description

Mullite Insulation Brick is the patent product of our company, and it features in extremely good heat shock stabillity and high temperature strength. It can last 5 times longer than ordinary mullite insulated brick. Especially when applied in the shuttle kiln with high application frequency and large temperature changes, it shows its superiority better. the bricks are exported worldwidely.
