Microporous Board for Aluminum Industry
Microporous boards are specifically engineered for high-temperature industrial applications, offering exceptional thermal efficiency with a conductivity lower than that of still air.
- Thermal Conductivity Lower Than That of Still Air
- Excellent High-Temperature Stability
- Lightweight and Efficient
- Environmentally Friendly and Non-Toxic
- Resistance to Thermal Shock
What is Microporous Board?
Microporous boards are high-performance insulation materials designed to reduce heat transfer through conduction, convection, and radiation. Featuring a unique nanoporous structure made from ultra-fine silica, these boards achieve thermal conductivity lower than that of static air, making them one of the most efficient insulation solutions available. The boards provide 3-6 times the insulation efficiency compared to conventional materials like perlite and calcium silicate, enabling improved temperature stability, energy savings, and enhanced performance in extreme environments.

Applications and Benefits of Microporous Boards
Microporous boards are widely used in industries where high-temperature insulation is essential, such as aluminum processing, steel manufacturing, and ceramics. Due to their lightweight and space-saving properties, they are suitable for applications like holding furnaces, melting furnaces, and ladles, delivering excellent resistance to thermal shock. Their thin profile allows for easy installation in tight spaces without sacrificing insulation quality, offering a durable, long-term solution that supports energy efficiency and operational reliability in demanding industrial processes.
Key Features of Microporous Boards
Ultra-Low Thermal Conductivity: Designed with a nanoporous structure, this board minimizes all three modes of heat transfer, achieving thermal conductivity levels even lower than static air and delivering 3-6 times better insulation than standard materials.
High-Temperature Stability: Withstands temperatures up to 1200°C without compromising insulation quality.
Lightweight Efficiency: Delivers effective insulation with a weight reduction of over 50%, ideal for confined spaces.
Eco-Friendly and Safe: Free from harmful fibers and toxic elements, fully recyclable, and meets environmental compliance standards.
Thermal Shock Resistant: Engineered to remain stable under rapid temperature fluctuations, perfect for harsh industrial conditions.
Molding Method
Microporous boards are molded using machine press molding (primarily for boards):
- Unlike bricks, microporous boards require no drying or sintering.
- After pressing, the boards can be cut to meet various size specifications.
- For glass fiber cloth-covered types, there are two production methods:
a. The powder is placed into a fiberglass bag and then pressed, resulting in cambered edges.
b. After pressing and molding, the boards are wrapped and cut, creating right-angle edges.
What makes microporous board thermal conductivity lower than still air?
Microporous boards are engineered with a unique nanoporous structure that, combined with specific additives, significantly minimizes heat transfer through conduction, convection, and radiation across diverse temperature ranges. This high-performance insulation surpasses traditional materials like mineral wool, perlite, calcium silicate, ceramic fibers, and even advanced options like aerogel felts. Remarkably, the thermal conductivity of microporous board often falls below that of static air at most operating temperatures.
Advantages of Microporous Board:
- Nanoscopic Structure: Small particle size reduces contact, lowering heat conduction.
- Nanoporous Composition: Tiny pores (around 20nm) trap gases, nearly eliminating internal convection.
- Anti-Infrared Properties: Specialized powders block infrared radiation, further limiting heat transfer in high-temperature settings.
These characteristics make microporous materials ideal for industrial applications, offering exceptional thermal insulation and reliability in extreme environments.
Multiple Surface Covering Choices
Depending on factors like product type, operating temperature, handling requirements, and environmental conditions, microporous boards are available with various standard covering materials. These include:
– Aluminum Foil Covering
– Aluminum Foil Cloth Covering
– POF (Polyolefin) Film Covering
– Non-woven Fabric Covering
– Fiberglass Cloth Covering
Each covering material is chosen to suit specific application needs, ensuring optimal performance and durability in diverse industrial and operational settings.
