Vermiculite Coated Fiberglass Fabric

Compared with standard fiberglass fabric, vermiculite coated fiberglass fabric provides better surface stability when exposed to severe heat. The vermiculite treatment helps spread heat across the fabric surface and protects the glass fiber structure from direct flame and hot abrasion. This makes it a practical choice for customers who need a flexible, non-combustible and cost-effective fabric for medium to severe thermal protection applications.

Anhui Parker New Material Co., Ltd supplies vermiculite fiberglass cloth in multiple thicknesses from 0.8 mm to 3.0 mm. Custom width, roll length, cutting, sewing and fabricated insulation parts are available for industrial buyers, distributors and OEM thermal protection projects.

Why Use Vermiculite Coated Fiberglass Fabric?

Vermiculite is a naturally occurring mineral with a plate-like structure. When applied to fiberglass fabric, it creates a mineral-based protective surface that improves heat resistance, flame shielding and abrasion performance. The coating does not rely on silicone, PTFE or aluminum foil, so it is suitable for applications where users need a dry, mineral-coated fabric for direct thermal exposure.

• Improves resistance to direct flame and radiant heat compared with untreated fiberglass fabric.
• Helps protect the fiberglass base yarn from heat attack and surface abrasion.
• Suitable for welding protection, furnace insulation and industrial heat containment.
• Flexible enough for wrapping, cutting, sewing and fabrication into custom insulation parts.
• Non-combustible fiberglass construction for demanding high-temperature environments.
• Available in several weights and thicknesses for different insulation and durability requirements.

FAQ

What is vermiculite coated fiberglass fabric?

Vermiculite coated fiberglass fabric is a woven fiberglass cloth treated with a mineral-based vermiculite coating. The coating improves heat resistance, flame shielding and surface durability for industrial thermal protection applications.

What temperature can vermiculite fiberglass cloth withstand?

This fabric is designed for high-temperature applications up to 815°C / 1500°F depending on exposure time, heat source, airflow, installation method and mechanical load.

Is vermiculite coated fiberglass fabric suitable for welding blankets?

Yes. It is commonly used for welding blankets, welding screens and spark protection where a flexible, non-combustible and abrasion-resistant fabric is required.

Can this fabric be sewn into removable insulation covers?

Yes. Vermiculite coated fiberglass fabric can be cut and sewn into removable covers for valves, flanges, exhaust systems, machinery and other hot industrial equipment.

What is the difference between vermiculite coated fiberglass fabric and silicone coated fiberglass fabric?

Vermiculite coated fiberglass fabric uses a dry mineral coating for high-temperature heat and flame resistance. Silicone coated fiberglass fabric provides better oil, water and weather resistance, but its surface coating is different and may not be suitable for the same direct high-temperature exposure conditions.

Can you supply custom thickness or roll size?

Yes. Standard thicknesses are available from 0.8 mm to 3.0 mm. Custom width, roll length, cut pieces and fabricated insulation products can be supplied upon request.
