High-Performance High-Temperature Insulation Material: Aluminum Foil Ceramic Fiber Blanket

Product Introduction

The aluminum foil ceramic fiber blanket is a high-performance insulation material composed of a premium ceramic fiber blanket laminated with multiple layers of high-strength aluminum foil. It features outstanding thermal insulation, high-temperature resistance, corrosion resistance, and mechanical strength, effectively reducing equipment heat loss and improving energy efficiency. With excellent flexibility and workability, this product is widely used for insulation, thermal protection, and shielding in high-temperature equipment across industries such as metallurgy, petrochemicals, power generation, machinery manufacturing, shipbuilding, and aerospace.

The aluminum foil layer not only enhances the weather resistance and mechanical protection of the fiber blanket but also reflects thermal radiation, significantly improving overall insulation performance. Additionally, the material is lightweight, thermally shock-resistant, corrosion-resistant, and environmentally safe, meeting the high standards of modern industries for energy conservation, emission reduction, and safety protection.

Product Structure and Composition

The aluminum foil ceramic fiber blanket primarily consists of the following components:

(1) Ceramic Fiber Blanket Base

Made from high-purity ceramic fibers using spinning or felting processes, the fiber structure is dense and uniform with moderate density, offering extremely low thermal conductivity and excellent high-temperature resistance.

(2) Aluminum Foil Composite Layer

The surface is laminated with multiple layers of composite aluminum foil, typically with a thickness ranging from 0.06 to 0.12 mm. This provides good corrosion resistance, wear resistance, and thermal radiation reflection. The multi-layer structure ensures the aluminum foil is firmly adhered to the fiber blanket surface, enhancing overall mechanical strength and protective performance.

(3) Adhesive

To strengthen the bond between the aluminum foil and the fiber blanket, a special high-temperature heat-resistant adhesive is used. This adhesive is non-toxic, harmless, and does not compromise the product's environmental performance.

(4) Surface Treatment (Optional)

Some products undergo surface coating treatments to add features such as waterproofing, oil resistance, and dust resistance, making them suitable for more complex operating environments.

Technical Parameters

Core Performance Advantages

(1) Outstanding High-Temperature Insulation Performance

The aluminum foil ceramic fiber blanket combines the low thermal conductivity of ceramic fiber blankets with the high reflectivity of the aluminum foil layer. This effectively blocks heat conduction and radiation, significantly reducing equipment surface temperatures and minimizing heat energy waste, thereby achieving energy-saving and consumption-reducing goals.

(2) Excellent Corrosion and Weather Resistance

The aluminum foil layer offers strong oxidation and corrosion resistance, effectively protecting the internal fiber material. This prevents performance degradation due to environmental moisture or acid-base corrosion, significantly extending the product's service life.

(3) Lightweight and Flexible, Easy to Install

The product is lightweight, highly flexible, and easy to cut and wrap around equipment surfaces of various complex shapes. Its quick and convenient installation reduces construction difficulty and time.

(4) Strong Moisture and Dust Resistance

The multi-layer aluminum foil composite structure prevents moisture from penetrating the fiber blanket, effectively avoiding performance deterioration caused by dampness and ensuring long-term, stable insulation effectiveness.

(5) Environmentally Safe and Compliant with International Standards

Free from asbestos and harmful substances, with no VOC emissions. Complies with EU RoHS and REACH environmental directives and international environmental certifications. Safe and non-toxic, making it suitable for applications with strict environmental requirements.
