4x4mm PTFE Coated Fiberglass Open Mesh Fabric
1. Product Overview
4x4mm PTFE coated fiberglass open mesh fabric is the standard industrial conveying medium constructed from high-tensile woven E-glass yarns coated and sintered with polytetrafluoroethylene (PTFE) dispersion. The 4x4mm square aperture provides consistent airflow permeability and thermal transfer while providing physical support to prevent conveyed parts and fabrics from sagging. The non-stick fluoropolymer surface prevents inks, adhesives, and polymer residues from adhering to the yarns, while the dimensionally stable fiberglass core resists elongation, tracking deviation, and thermal degradation under continuous conveyor tension.
