Lanmar #632-3R is a 3 mil PTFE coated fiberglass tape with a blue release liner, engineered for demanding applications that require exceptional release, chemical resistance, and a low coefficient of friction. The premium PTFE coating delivers reliable non-stick performance, while the release liner allows for clean handling and precise application.

Ideal for Heat Sealing & Packaging

#632-3R is widely used in packaging operations for sealing cartons, securing plastic bags, and protecting heat-sensitive materials. Its high-temperature resistance and superior release properties help prevent adhesive buildup and improve sealing efficiency.

Plastics Processing & Mold Release

This tape is commonly used as a mold release surface and extrusion barrier in plastics manufacturing. It prevents molten plastic from sticking to molds and equipment, improving production efficiency and reducing downtime.

Roll Covering & Industrial Release

In printing, paper, and textile manufacturing, #632-3R provides a durable non-stick surface for rollers. Its chemical resistance and low-friction PTFE surface help materials release easily, improving throughput and reducing maintenance.

uPVC Window Welding & Fabrication

#632-3R is also used in uPVC window welding, where it supports clean weld seams and smooth material movement during assembly, ensuring precise alignment and consistent results.

Additional Industrial Applications

Common uses include:

• Lining chutes and hoppers for bulk material handling

• Heat sealing thermal insulation materials

• Release aid for adhesive-backed products

Available in widths up to 42 inches, Lanmar #632-3R PTFE coated fiberglass tape offers reliable performance and easy application for a wide range of high-temperature industrial processes.
