High-Performance Insulation Solutions for High-Temperature Applications

High Temperature Insulation

Engineered for Extremes - Proven by Science

High-temperature insulation is essential wherever industrial systems operate under extreme thermal conditions. The goal is clear: maximize energy efficiency, safety, and durability while minimizing heat loss, space, and maintenance.

Our microporous insulation represents a new generation of high-performance materials, engineered to deliver the lowest possible thermal conductivity even at temperatures above 1000 °C — using only 1/4 to 1/6 of the thickness required by traditional insulations such as ceramic fiber, calcium silicate, or insulation bricks.

This enables thinner, lighter designs that maximize energy efficiency and space optimization, ensure precise process control, and create safer working conditions—all while supporting your sustainability goals.

WHY MICROPOROUS TECHNOLOGY IS SUPERIOR FOR HIGH-TEMPERATURE APPLICATIONS

Our microporous insulation products achieve superior thermal performance by simultaneously tackling conduction, convection, and radiation. Its nano-porous fumed silica structure limits gas and solid conduction, while added opacifiers block radiative heat. This synergy creates an insulation with thermal conductivity near the theoretical limit of still air, maintaining efficacy in extreme environments.

Outstanding Thermal Performance: Key Technical Highlights

The following technical data for our TT 1000 classic board demonstrates the high performance of our microporous insulation materials:

Property Value
Thermal Conductivity (W/m·K) 0.021 @ 20°C
0.023 @ 200 °C
0.026 @ 400 °C
0.030 @ 600 °C
0.034 @ 800 °C
Continuous Service Temperature Up to 950 °C
Peak Temperature for Fire Protection (≤4h) 1200 °C
Nominal Density ≈ 270 kg/m³, other density can be customized
Shrinkage < 2 % @ 950 °C / 12 h (all sides)
< 0.5 % @ 1000 °C / 12 h (one side)
Compressive Strength (10% deformation) ≥ 0.27 MPa

Dimensional and Chemical Stability

Our microporous outstanding dimensional stability prevents thermal gaps, ensures consistent performance under cycling, and extends the operational life of thermal systems. The material’s fine-particle structure also offers excellent resistance to thermal shock and oxidation, maintaining integrity even after repeated heating and cooling cycles.

Microporous insulation

Versatile, Engineered Microporous Insulation

Our microporous insulation products with different shapes and processed styles are designed for versatile integration into complex thermal assemblies.

Board or panel-shaped products can be cut, drilled, or machined using standard woodworking tools. Board shaped products are available in naked, wrapped, or laminated forms (e.g., aluminum foil, glass tissue) to suit specific applications.

For large-scale production, custom molding and net-shape pressing help minimize waste and improve precision.

Our boards or panels can also be combined with other insulators to create multi-layer configurations — optimizing both performance and cost efficiency across different temperature zones within the same system.

Microporous insulation

Ecologically Effective Throughout the Entire Life Span

Our microporous insulation materials are free of organic binding agents. They are made of silica (silicon dioxide) or alumina, an inorganic opacifying agent, and non-hazardous fibres that are resistant to high temperatures. These inherently stable products are long-lasting, do not rot, are vermin-resistant and easy to recycle.
