0.25mm PTFE Coated Fiberglass Adhesive Fabric (With Release Liner)
1. Product Overview
0.25mm PTFE coated fiberglass adhesive fabric is an engineered self-adhesive composite constructed from a high-density woven E-glass substrate impregnated and sintered with polytetrafluoroethylene (PTFE) dispersion, coated on one side with high-temperature silicone pressure-sensitive adhesive (PSA), and protected by a release liner. The reinforced 0.25mm profile delivers high tensile strength, puncture durability, and extended wear life under mechanical abrasion. The non-porous fluoropolymer surface provides complete non-stick release against molten plastics, viscous adhesives, and hot resins, while the silicone adhesive layer ensures high peel strength on metal and plastic surfaces up to 260°C with residue-free removal upon changeover.
2. Core Technical Parameters

-
Top Coating: Sintered industrial polytetrafluoroethylene (PTFE / Teflon)
-
Adhesive System: High-temperature pressure-sensitive silicone adhesive (PSA)
-
Backing Protection: Yellow corrugated PVC or white PE release liner (preserves adhesive tack and facilitates wide-format slitting and die-cutting)
-
Nominal Overall Thickness: 0.25mm (excluding release liner)
-
Operating Temperature: -70°C to +260°C
-
Key Characteristics: Heavy-gauge wear resistance, non-stick release surface, high peel adhesion, residue-free removal upon changeover, flame retardant, chemical and solvent resistant
3. Common Applications
-
Heavy-duty heat-sealing jaw, wire, and platen wrapping on bulk bag-making machinery, shrink-wrap tunnels, and vacuum packaging systems
-
Low-friction, wear-resistant anti-abrasion linings for hoppers, chutes, slide guides, and feed bins handling abrasive materials
-
Protective roller wrapping on continuous laminators, extrusion coaters, and textile sizing machinery to eliminate adhesive and polymer buildup
-
Precision stamped and die-cut heat-resistant release pads, electrical insulating shims, and mechanical sliding gaskets
