Product catalog summary

Introduction
Thermiculite® 866 is a specialized sealing material designed for Solid Oxide Fuel Cells (SOFC). It is recognized for its high performance in various SOFC applications globally, utilizing chemically exfoliated vermiculite technology developed by Flexitallic.

Material Composition and Properties
Thermiculite® 866 is made from vermiculite, a mineral related to mica, known for its high temperature resistance, chemical resistance, and electrical insulation properties. The exfoliation process separates vermiculite into thin, flexible crystal plates that adhere to each other, forming a flexible film. This material is free of organic content, ensuring no burn-off at high temperatures.

Performance Characteristics
Thermiculite® 866 is stable at temperatures up to 1000°C, maintaining excellent seal integrity without thermal degradation. It is soft, compressible, and can be cut into complex shapes. The material does not become porous over time, ensuring low leakage rates even through thermal cycles.

Thermiculite® 866 LS
This variant achieves sealing at low surface stresses and maintains high sealing efficiency during thermal cycling. It features a glass coating that compensates for surface irregularities and forms a seal at operational temperatures without requiring an initial sintering cycle.

Case Studies and Testing
Figures in the document demonstrate the robustness and sealing performance of Thermiculite® 866 and 866 LS, showing stable performance during thermal cycling and low leakage rates under various conditions.

Applications and Benefits
Thermiculite® 866 is the preferred choice for SOFC developers due to its ability to maintain seals without thickness reduction or performance loss during thermal cycling. It is suitable for complex sealing arrangements and offers extended lifetime performance.

Global Presence
The Flexitallic Group operates globally, providing specialized sealing solutions across various industries, including oil and gas, power generation, and petrochemicals, with operations in multiple countries and a network of partners and distributors.
