Product Description

High Purity Ceramic Fiber Blanket Precision Furnace Alumina Silicate Needled Roll

Product Description

High Purity Ceramic Fiber Blanket is a needled alumina-silicate insulation roll made from refined fiber with a low shot content. The cleaner fiber structure and elevated alumina content deliver more consistent thermal performance and better resilience than standard-grade blankets.

Designed for precision furnaces and laboratory kilns, the blanket supports stable, repeatable temperature control. Its low shot content also reduces dust during handling, keeping installation cleaner and reducing airborne fiber in sensitive production areas.

Like all needled ceramic blankets, it contains no organic binders and remains non-combustible and chemically stable, providing a clean and durable thermal barrier for sensitive high-temperature processes.

Product Features

Binder-Free Needled Construction – Mechanically interlocked fibers keep performance stable without organic binders.

High Purity Alumina Silicate – Refined fiber with elevated alumina content delivers consistent performance and resilience.

Precision Furnace Insulation – Supports stable, repeatable temperature control in precision furnaces and lab kilns.

Low Shot Content – Fewer unfiberized particles mean less dust and cleaner installation.

Class A1 Non-Combustible – Inorganic body adds fire safety to the insulation layer.
