Lanmar #632-3 is a 3 mil PTFE coated fiberglass tape with acrylic adhesive engineered for reliable performance in high-temperature and industrial processing environments. The premium PTFE coating delivers excellent release, outstanding chemical resistance, and a low coefficient of friction, while the acrylic adhesive provides strong bonding to a wide range of surfaces.

Ideal for Heat Sealing & Packaging

#632-3 is widely used in packaging applications that involve heat sealing and heat-sensitive materials. Its non-stick surface helps prevent adhesive buildup on sealing equipment, ensuring clean seals, improved efficiency, and reduced downtime.

Proven Performance in Plastics Processing

In plastics manufacturing, this tape performs as an effective mold release surface and extrusion barrier. It helps prevent molten plastic from sticking to equipment, supporting smooth production and consistent part quality.

Roll Covering & Industrial Release Applications

#632-3 is commonly used to protect rollers in printing, paper, and textile manufacturing. The durable PTFE surface resists chemicals and allows materials to release easily, improving throughput and reducing maintenance.

uPVC Window Welding & High-Temperature Fabrication

The tape’s heat resistance and low-friction surface make it ideal for uPVC window welding, where it supports clean weld seams, precise alignment, and consistent assembly performance.

Versatile Industrial Applications

Additional uses include:

• Heat sealing thermal insulation materials

• Release aid for adhesive-backed products

• Lining for chutes and hoppers

• Barrier protection during coating and plating processes

Lanmar #632-3 PTFE coated fiberglass tape provides a dependable non-stick solution for industries that require heat resistance, chemical resistance, and low friction performance.
