Product Description

Low Shot High Purity Grade Aluminum Silicate Fiber Board Refractory Backup 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 purity grade is made with low shot content for cleaner, more uniform insulation. It suits duties where low contamination and stable performance matter, such as precision equipment, laboratory and process furnaces, and refractory backup layers.

The rigid board is easy to cut and machine to size, resists thermal shock and is non-combustible and chemically stable. 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

Low Shot Content Board – Cleaner, more uniform insulation for precision duty.

High Purity Fiber Board – Low contamination for critical equipment.

Rigid Formed Structure – Stable dimensions and good mechanical strength.

Excellent Thermal Insulation – Uniform density reduces heat loss.

Class A1 Non Combustible – Will not burn or smoke in service.

Easy Installation – Easy to machine and fit on site.
