Lanmar #645-5 is a high-performance 5 mil PTFE coated fiberglass tape with high-temperature silicone adhesive, engineered for demanding industrial applications that require reliable non-stick release, chemical resistance, and low friction. The standard-weight PTFE coating delivers consistent performance in high-heat environments where standard tapes fail.
The smooth PTFE surface helps prevent sticking and residue buildup, improving efficiency and reducing downtime in continuous processing and sealing operations.
#645-5 maintains its integrity under elevated temperatures, making it a dependable choice for heat sealing and high-temperature processing where clean release and consistent results are critical.
The PTFE coating resists many chemicals commonly encountered in manufacturing, helping extend service life and maintain performance in harsh conditions.
With a low coefficient of friction, #645-5 supports smooth movement on rollers, guides, and contact surfaces—reducing drag, wear, and processing interruptions.
#645-5 is widely used in:
Heat sealing and packaging lines
Plastics processing and mold release
Roll covering in printing, paper, and textile manufacturing
uPVC window welding and fabrication
Low-friction rollers, guides, and wear surfaces
High-temperature gasketing, sealing, and heat shielding
Lanmar #645-5 PTFE coated fiberglass tape provides durable non-stick performance, high heat resistance, and long service life for demanding industrial and packaging applications.
