Fiberglass Filter Cloth
Industrial-Grade Fiberglass Filter Cloth for Extreme High-Temperature Filtration
Factory-direct supply of premium fiberglass filter fabrics in rolls. Engineered to withstand continuous operating temperatures up to 260°C (500°F). We offer customized surface treatments including PTFE membrane, PTFE dipping, and Graphite to meet your exact industrial dust collection needs.
- Extreme Heat Resistance Capable of operating continuously at 240°C and handling temperature surges up to 260°C, making it the ultimate choice for high-temp flue gas environments.
- Custom Surface Treatments We apply specialized finishes such as PTFE membrane (for surface filtration), silicone, graphite, and water/oil repellent treatments to enhance durability, acid/alkali resistance, and dust release.
- High Tensile Strength & Stability Woven from premium E-glass fibers, our cloth offers excellent dimensional stability, minimal elongation, and high tensile strength to prevent tearing during baghouse pulse-jet cleaning.

Woven Fiberglass Filter Cloth
| Item | Non-woven Fiberglass Filter Bags | Woven Fiberglass Filter Bags |
|---|---|---|
| Material Structure | Fiberglass fibers are mechanically needled into a felt structure, usually with a supporting scrim. | Fiberglass yarns are interlaced in warp and weft to form a stable woven fabric. |
| Typical Temperature Capability | Typically up to 180–240°C, depending on fiber construction and finishing. | Up to 260°C continuous operation in selected constructions. |
| Filtration Performance | Three-dimensional felt structure provides good fine dust capture and dust-holding capacity. | Filtration performance depends on weave density and surface treatment; often selected for stable high-temperature operation. |
| Dimensional Stability | More flexible, with good adaptability to different baghouse designs. | High tensile strength, low elongation, and excellent dimensional stability. |
| Best-Fit Applications | Fine dust collection, pulse-jet baghouses, and medium-to-high-temperature filtration. | High-temperature baghouses requiring low stretch and stable bag dimensions. |
