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.

Non-woven Fiberglass Filter Cloth

Woven Fiberglass Filter Cloth

ItemNon-woven Fiberglass Filter BagsWoven Fiberglass Filter Bags
Manufacturing processGlass fibers are combined physically or chemically using non-woven processes such as needle punching.Glass fiber yarn is woven into cloth. The yarn is arranged in a certain warp and weft to form a regular fabric structure.
High temperature resistanceHigher, slightly lower than woven type.Extremely high, can withstand high temperature environment, suitable for use under high temperature conditions.
Mechanical strengthLow, but better softness and adaptability.Strong, wear-resistant, suitable for harsh working environment.
Filtration efficiencyHigh, good air permeability, suitable for capturing fine particles.High, but relatively poor air permeability.
Applicable environmentMedium temperature, low corrosion and fine dust particles environment.High temperature, high corrosion and high wear environment.
