PTFE Coated Fiberglass Adhesive Tape
1. Product Overview
PTFE coated fiberglass adhesive tape is an engineered self-adhesive composite constructed from a precision woven E-glass substrate impregnated with polytetrafluoroethylene (PTFE) dispersion, coated on one side with a high-temperature pressure-sensitive silicone adhesive (PSA), and backed with a protective release liner. The smooth fluoropolymer working face provides complete non-stick release against hot polymers, melted packaging films, and viscous adhesives. The silicone adhesive layer establishes a strong bond to metal and plastic machinery surfaces under continuous operating temperatures up to 260°C while peeling off cleanly without leaving adhesive residue during maintenance replacement.
