Product Description

Insulating firebricks are classified under temperature between 1300ºC and 1700ºC, manufactured from high purity alumina clay by mixing, press-forming, drying, sintering and machining. Bricks contain carefully-graded organic fillers which are burned out during sintering to give a uniform controllable pore structure. This technique makes product feature low thermal conductivity and excellent heat insulation

Our high alumina poly light weight fire bricks use selected raw material of calcined bauxite, fire clay and other additive,adopt new manufacture method of burning up adding polypropylene granular and firing under 1300-1500ºC in tunnel kiln.

Characteristics of our high alumina insulation fire brick (YZHA-IFB):
1)High cold crushing strength
2)High softing temperature under load
3)Accurate dimension
4)Good thermal shock resistance
5)Low thermal conductivity
6)Stable heat capability
7)Small reheating liner change

Application of our high alumina insulation fire brick IFB(YZHA-IFB) :
Widely used in insulating layers of various thermal equipments and linings where no high temperature corrosion and scouring occurs.When direct touch flame, the highest temperature can not over 1350ºC.
