Fireproofing thermal protection industrial fiberglass Fabric

Fiberglass fabric is a high-performance industrial fabric made from glass fibers and woven by special manufacturing processes.The product has the advantages of high strength, stable tension, and few appearance defects. It can be widely used in PTFE, silicone, PVA, PVC and acrylic coating industries. The main product specifications are: 1080, 2116, 7628, 7630, 116, 128, 141, 3732, 3784, 3788, etc. The maximum width of the glass fiber cloth can reach about 5 meters; the thickness range is: 0.05mm~1.2mm; the gram weight range is: 40g/square~2000g/square; weaving method: plain, twill, satin, leno; we can also design, develop and mass produce various fiberglass fabric according to customer requirements.

Fireproofing Thermal Protection Industrial Fiberglass Fabric

Industrial-grade fiberglass fabric engineered for fireproofing and thermal protection in demanding environments. The fabric is produced from continuous filament yarns woven into a dense structure, then treated with a fire-retardant finish that achieves a limiting oxygen index of 35% or higher. Thermal conductivity remains below 0.042 W/m·K at 600 °C, and the material retains dimensional stability under sustained heat exposure. Customized solutions are available to meet specific client requirements, from mesh configuration and coating selection to roll dimensions and packaging. All products are manufactured in accordance with international standards including ISO 9001, ASTM, and EN specifications.

Custom Design ISO 9001 ASTM Compliant B2B Supply

Fireproofing Performance

LOI of 35% or higher with self-extinguishing behavior. The fabric does not propagate flame and resists ignition under continuous heat exposure. Fire-retardant treatment is integrated into the fiber structure, not applied as a surface coating.

Thermal Protection

Thermal conductivity of 0.042 W/m·K at 600 °C. The material creates a stable thermal barrier that reduces heat transfer to protected surfaces. Operating temperature range extends to 600 °C continuous, with short-term peaks up to 750 °C.

Custom Manufacturing

Tailored mesh openings, thickness variations from 1.5 mm to 8.0 mm, and optional coatings including silicone, vermiculite, and ceramic dispersions. Roll widths and lengths configured to client production requirements.

International Compliance

Manufactured under ISO 9001 quality management. Tested to ASTM D2863 (LOI), ASTM C518 (thermal conductivity), ASTM D5035 (tensile strength), and EN 13501-1 fire classification. Documentation available for compliance verification.

Common Questions

What customization options are available?

Thickness from 1.5 to 8.0 mm, mesh opening from 1.5 to 5.0 mm, coating type (silicone, vermiculite, ceramic), roll width up to 2000 mm, and length per client specification. Custom die-cutting and slitting services are also offered.

How is the fire-retardant treatment applied?

The fire-retardant agent is incorporated during the fiber sizing stage, before weaving and expansion. This ensures the treatment is distributed throughout the fiber structure rather than as a surface layer that may wear off.

What documentation is provided for compliance?

Material certificates including LOI test reports, thermal conductivity data, tensile strength results, and fire classification certificates per EN 13501-1 are available. Additional testing can be arranged for specific client standards.

What is the minimum order quantity for custom products?

Minimum order quantity depends on the customization scope. Standard configurations start at 500 square meters. Custom-coated or die-cut products may require higher minimums based on tooling and setup requirements.
