Lanmar #645-6 is a high-performance 6 mil PTFE coated fiberglass tape with high-temperature silicone adhesive, engineered for demanding industrial applications where heat resistance, non-stick release, chemical resistance, and low friction are essential. The standard-weight PTFE coating provides consistent release performance and durability in high-heat processing environments.
The smooth PTFE surface helps prevent sticking and residue buildup, supporting clean processing and reducing downtime on heat sealing and contact surfaces.
#645-6 maintains its integrity in elevated temperatures and resists many chemicals commonly encountered in industrial manufacturing, helping extend service life in harsh environments.
With a low coefficient of friction, this tape improves material movement on rollers, guides, and conveyor/contact areas—reducing drag, wear, and processing interruptions.
#645-6 is widely used in:
Heat sealing and packaging operations
Plastics processing and mold release
Roll covering in printing, paper, and textile manufacturing
uPVC window welding and fabrication
Conveyor systems, rollers, and wear surfaces
Composite manufacturing as a release surface
Insulation wrapping and thermal protection in industrial equipment
Lanmar #645-6 PTFE coated fiberglass tape delivers durable non-stick performance, high heat resistance, and dependable adhesion for demanding industrial and packaging environments.
