Product Description

High Alumina Grade Aluminum Silicate Fiber Board 1350C Refractory Lining Panel

Product Description

Aluminum Silicate Fiber Board, also known as ceramic fiber board or alumina-silicate insulation board, is a rigid high-temperature insulation board manufactured from high-purity alumina-silicate fibers through a wet vacuum forming process. This forming method gives uniform fiber distribution and consistent density, producing a board with good mechanical strength, stable dimensions and dependable thermal performance at elevated temperature.

This high alumina grade carries a higher Al₂O₃ content for greater stability at high temperature. It works as hot-face or backup lining in steel, glass, ceramic and cement furnaces and kilns, and in ducts and ladles.

The rigid board resists thermal shock, chemical attack and mechanical load, and it is non-combustible and asbestos free. A small amount of organic binder gives the board handling strength and burns off gradually on first heating around 250–400°C, producing a light, brief smoke.

Product Features

High Temperature Resistance – Higher alumina content for stability at heat.

Refractory Lining Board – Hot-face or backup lining for furnaces and kilns.

High Alumina Board – Higher Al₂O₃ content for refractory duty.

Outstanding Thermal Shock Resistance – Resists rapid heating and cooling without cracking.

Excellent Chemical Stability – Resists most acids, alkalies and solvents.

Class A1 Non Combustible – Adds passive fire protection to the lining.
