Flame-resistant fabric made from glass fabric with vermiculite coating

Glass fabric with double-sided vermiculite coating has an increased temperature resistance of up to 1000 °C and can even withstand short-term exposure to 1200 °C. The vermiculite flakes, which are mineral-based, are applied to the glass fabric through an aqueous dispersion treatment, forming a "protective shell" that melts at high temperatures to protect the glass fabric from heat exposure—such as direct flames, welding spatter, or molten metal splashes.

Technical Characteristics

• The vermiculite coating makes the glass fabric even more resistant to high temperatures. It withstands extreme heat exposure of up to 1000 °C without losing its structural integrity. It can even handle short-term exposure to 1200 °C and is resistant to molten metal splashes.
• Vermiculite acts as a protective barrier against flames, sparks, and welding spatter, making these materials an ideal choice for fire protection, welding, and grinding applications.
• Glass fabrics with vermiculite coating have improved mechanical strength, making them ideally suited for harsh and extreme conditions.
• Despite its robust properties, the material remains flexible and can be easily cut and processed, making it versatile for various applications.
• Also available optionally with woven V4A steel reinforcement.

Application Examples

• Glass fabric with vermiculite is often used as a protective material in the fire protection industry, as a welding curtain and welding blanket, or in areas that need to be protected from sparks and welding spatter, such as shipbuilding and plant construction.
• In the metal industry, the material protects against hot metal splashes, sparks, and intense heat, thereby improving safety in work environments.
