Lanmar #635-6R is a premium PTFE coated fiberglass tape with high-temperature silicone adhesive and a yellow dimpled release liner, designed for demanding heat sealing and industrial applications. The heavy PTFE coating provides exceptional release, excellent chemical resistance, and a low coefficient of friction for reliable high-heat performance.

Superior Non-Stick Release & Low Friction

The smooth PTFE surface prevents materials from sticking, allowing for clean release and reduced residue. This helps improve efficiency, minimize downtime, and protect equipment in high-temperature processing environments.

Chemical Resistance for Harsh Environments

The PTFE coating resists a wide range of chemicals, ensuring durability and long service life in applications where exposure to corrosive substances is common.

Easy Application with Dimpled Release Liner

A yellow dimpled release liner protects the adhesive during storage and handling while enabling quick, clean installation and a smooth working surface.

Heat Sealing & Packaging Applications

#635-6R is widely used for heat sealing polyethylene, polypropylene, and laminated films, delivering consistent seals and reliable package integrity.

Plastics Processing & Mold Release

Ideal for mold release and extrusion processes, this tape prevents molten plastic from sticking to equipment, improving productivity and reducing maintenance.

Roll Covering & uPVC Window Welding

Commonly used for roller protection in printing, paper, and textile manufacturing and uPVC window welding, where it supports clean weld seams and precise alignment.

Lanmar #635-6R PTFE coated fiberglass tape offers dependable non-stick performance, high-temperature resistance, and easy installation for demanding industrial processes.
