#645-3 is an exceptional 3mil PTFE coated fiberglass tape featuring a high-performance silicone adhesive. This pressure-sensitive tape is designed to meet the demanding requirements of high-temperature applications, delivering strong release properties, excellent chemical resistance, and a low coefficient of friction.

With its standard weight coating of PTFE, #645-3 provides reliable release properties, ensuring that materials or products can be easily released without sticking or leaving behind residue. This is particularly beneficial in industries such as packaging, plastics, roll covering, and uPVC window welding, where efficient and precise processing is essential.

One notable advantage of #645-3 is its outstanding resistance to high temperatures, allowing it to maintain its integrity and performance in extreme heat conditions. This makes it a reliable choice for applications involving heat sealing, where the tape acts as a barrier to prevent unwanted adhesion during the sealing process.

The tape's chemical resistance is another valuable characteristic, protecting it from degradation when exposed to various chemicals commonly encountered in industrial processes. This ensures the tape's longevity and reliability, even in challenging working environments.

This tape is particularly well-suited for high-temperature applications in the packaging, plastics, roll covering, and uPVC window welding industries. Whether with a release liner or self-wound, #645-3 offers reliability, efficiency, and durability in demanding environments.
