Porous Fabric
Porous Bleeder & Filter Cloth
Taconic porous bleeder and filter cloth materials are engineered for applications requiring air permeability, breathability, drainage, filtering, drying, or outgassing.
Unlike smooth PTFE coated fabrics, porous constructions allow airflow or vapor movement through the fabric surface while maintaining useful release and process performance.
Porous PTFE fabrics are used in composite processing, drying systems, filtration-related applications, vacuum processes, and industrial operations where controlled permeability matters.

Fabric FAQ
Common questions about
porous fabric.
What is porous bleeder cloth used for?
Porous bleeder cloth is used in applications requiring airflow, outgassing, drainage, drying, or controlled permeability.
How is porous fabric different from standard PTFE fabric?
Porous fabric allows air or vapor movement through the construction, while standard PTFE fabric is typically a smoother, less permeable release surface.
Where are porous PTFE fabrics commonly used?
They are used in composite processing, drying, filtration-related processes, vacuum applications, and other industrial operations requiring breathability.
