Lanmar PTFE coated fiberglass tape combines the strength of a woven fiberglass backing with the non-stick, heat-resistant performance of PTFE. The result is a high-performance adhesive tape that maintains release, durability, and surface consistency in conditions where standard tapes fail.
Silicone adhesive (up to 500°F / 260°C)
Best for heat sealing equipment, packaging machinery, and high-temperature industrial processes where maximum heat resistance and long service life are required.
Acrylic adhesive (up to 350°F / 177°C)
A cost-effective option for moderate-temperature applications that still require reliable release, reduced friction, and dependable adhesion.
Both adhesive systems are available with or without a release liner (self-wound). Lanmar Premium Grade PTFE tapes feature a smooth, consistent surface finish with enhanced tensile strength, dimensional stability, and extended wear life ideal for heat sealing jaws and platens where surface quality impacts seal performance.
Heat sealing and packaging equipment (jaw covers, bar covers, platen liners)
Food processing conveyors and non-stick surfaces
Screen printing platens and release surfaces
Anti-friction guides, chutes, and wear surfaces
Mold release layers for composites manufacturing
Wire harness protection in aerospace and automotive assemblies
PTFE coated fiberglass tape is FDA-compliant for food contact applications. All rolls are available custom-slit to your required widths, and we can cross-reference many 3M 5151, Taconic, Saint-Gobain, and CS Hyde part numbers send your current spec for a direct match.
