Product Description:

Vacuum formed fiber ceramic rigid board is high performance insulation products manufactured from ceramic fiber (or with alumina fiber) and binders, with unique shot removing and vacuum forming process, provide excellent high temperature stability, extra low thermal conductivity, high compressive strength. 

Features;

Low heat storage and low thermal conductivity;

High compression strength;

Non –fragile materials and good toughness;

Accurate dimension and good palneness;

Structure homogeneity and easy machining;

Easy to install

Continual production, even fiber with stable property;

Excellent heat stability and thermal shock resistance 

Application:

Cement building industry, kiln back lining-thermal insulation;

Ceramic industry-lining of various kilns for thermal insulation;

Petrochemical and metallurgy industries- back linings, wall linings, and linings-thremal insulation;

Glass kiln lining and back lining thermal insulation;

Heat treatment furnace kiln back lining thermal insulation;

Aluminium factories-reduction cell firebricks back linings;
