Aluminized Ceramic Fiber Board

Product Introduction

Aluminized Ceramic Fiber Board enhances traditional ceramic fiber insulation with a reflective aluminum foil layer. This addition significantly improves radiant heat resistance, boosting overall thermal efficiency while providing a durable, dust-resistant surface. It retains all the core benefits of the base material-exceptional temperature resistance, low thermal conductivity, light weight, and fireproof properties.

Ideal for demanding applications where thermal management and cleanliness are critical, it is widely used in high-temperature furnace linings, power generation equipment, metallurgical and chemical processing, aerospace components, and construction fireproofing.

By combining superior insulation with effective heat reflection, Aluminized Ceramic Fiber Board delivers a reliable, energy-saving solution for modern industrial challenges.

Structure & Composition

Aluminum Foil Coated Ceramic Fiber Board is a high-performance composite material engineered with a strategic dual-layer design:

a. Core Layer: Ceramic Fiber Board
This foundational layer is manufactured from high-purity alumina-silica fibers via an advanced vacuum-forming process. It provides the board's essential characteristics: exceptional thermal insulation, remarkable resistance to thermal shock, and consistent structural integrity at high temperatures.

b. Composite Layer: Aluminum Foil
A specialized industrial-grade aluminum foil is permanently bonded to the core using high-temperature adhesives or hot-press lamination. This surface layer adds critical functionality, serving as a radiant heat barrier, a shield against moisture, and a tough, abrasion-resistant skin.

This optimized composition ensures superior performance in demanding high-temperature environments, delivering an ideal balance of thermal management, durability, and operational reliability.

Key Features of Aluminized Ceramic Fiber Board

1.Superior Thermal Insulation

The ceramic fiber core provides extremely low thermal conductivity, ensuring reliable performance in high-temperature environments up to 1260°C.

2.Radiant Heat Reflection

The aluminum foil layer reflects more than 95% of infrared radiation, dramatically reducing radiant heat loss and boosting overall energy efficiency.

3.Clean & Safe Operation

A sealed foil surface effectively contains ceramic fibers, preventing dusting and ensuring compliance with strict industrial cleanliness and safety standards.

4.Enhanced Structural Integrity

Our composite design delivers greater rigidity and superior compressive strength compared to conventional ceramic fiber boards.

5.Simplified Installation & Fabrication

Designed for convenience, the boards can be easily cut, drilled, and shaped on-site to accommodate complex layouts and specifications.

6.Moisture & Chemical Resistance

The integrated foil layer acts as a barrier against ambient moisture and corrosive chemicals, significantly prolonging service life.

FAQ

Q1: What is the recommended temperature range for aluminum foil ceramic fiber boards?

A1: The ceramic fiber substrate can withstand temperatures up to 1260°C. For long-term applications, we recommend operating within 1000°C–1150°C. The aluminum foil layer maintains structural stability up to 650°C. If your application involves higher temperatures, we suggest considering non-foil boards or alternative reflective coatings.

Q2: Will the aluminum foil peel off or oxidize under high temperatures?

A2: We use industrial-grade, oxidation-resistant aluminum foil, which is securely bonded to the substrate using high-temperature adhesives or hot-press technology to ensure strong adhesion and thermal stability. When used within the recommended temperature range (<650°C), delamination is unlikely. For outdoor or humid environments, we recommend edge sealing or waterproof treatments to help extend the product's service life.

Q3: Can the boards be customized in terms of size, thickness, or foil type?

A3: Yes, SUNTHERM offers a variety of customization options, including density (220–320 kg/m³), thickness (10–100 mm), standard sizes (e.g., 600×400 mm, 900×600 mm, 1200×1000 mm), and foil configurations such as single-sided, double-sided, perforated, or multi-layer designs.
