Product Description

Fireclay chamotte lining high alumina resistant fireproof heat refractory fire clay brick

 

Product Description

Laurel mullite 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.
 

Standard sizing: 230 x 114 x 65 mm
