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.

Reliable Non-Stick Release

The smooth PTFE surface helps prevent sticking and residue buildup, supporting clean processing and reducing downtime on heat sealing and contact surfaces.

High Temperature & Chemical Resistance

#645-6 maintains its integrity in elevated temperatures and resists many chemicals commonly encountered in industrial manufacturing, helping extend service life in harsh environments.

Low Friction for Smooth Material Flow

With a low coefficient of friction, this tape improves material movement on rollers, guides, and conveyor/contact areas—reducing drag, wear, and processing interruptions.

Common Applications

#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.
