0.18mm White PTFE Coated Fiberglass Adhesive Fabric (With Release Liner)
1. Product Overview
0.18mm white PTFE coated fiberglass adhesive fabric is an engineered self-adhesive composite constructed from a precision woven E-glass cloth impregnated with white polytetrafluoroethylene (PTFE) dispersion, coated on one side with high-temperature silicone pressure-sensitive adhesive (PSA), and protected by a release liner. The white fluoropolymer face provides visual cleanliness, low surface friction, and complete non-stick release against hot polymers and melted films. The silicone adhesive layer forms a high-strength bond to metals, plastics, and ceramics that withstands continuous thermal cycling up to 260°C while peeling off cleanly without leaving adhesive residue during maintenance replacement.
