PTFE Coated Fiberglass Open Mesh Conveyor Belts
1. Product Overview
PTFE coated fiberglass open mesh conveyor belts are engineered conveying fabrics constructed from high-tensile woven E-glass yarns impregnated and sintered with polytetrafluoroethylene (PTFE) dispersion. The open-grid aperture structure allows unrestricted airflow, thermal penetration, and liquid drainage, accelerating moisture evaporation and reducing thermal drying times. The non-porous fluoropolymer matrix prevents wet residues, adhesives, and resins from sticking to the mesh, while the dimensionally stable fiberglass core resists stretching, tracking deviation, and thermal degradation under continuous conveyor tension.
