Product Description
Fireclay chamotte lining high alumina resistant fireproof heat refractory fire clay brick
Laurel insulating bricks are made of bauxite,mullite, kaolin and other raw materials, suitable for applications from 1260ºC to 1550ºC. Each grade of brick is formulated to meet specific thermal and physical requirements. After firing, the bricks are machined to close dimensional tolerances.
The insulating brick has the properties of low thermal conductivity, lightweight, high porosity, thermal insulation, and good thermal shock resistance. Mainly used in industrial equipment lining, insulation layer, kiln door backing, roof and other parts.
Low bulk density
Low thermal conductivity
Good thermal shock resistance
High temperature resistance
Excellent thermal insulation effect
Special size and OEM Service also provide!

FAQ
- How do I choose between clay, high alumina, and mullite insulating bricks?
- It depends on your temperature requirements and chemical environment. Higher alumina content usually means better heat resistance.
- Can insulating bricks replace dense refractory bricks?
- Not completely. Insulating bricks are mainly used as backup insulation layers rather than load-bearing structures.
- Do insulating bricks easily break during installation?
- They are lighter but still strong enough for normal handling. Proper installation ensures durability.
