#635-6R is an exceptional PTFE coated fiberglass tape that boasts a high-performance silicone adhesive. Designed for high-temperature applications, this pressure-sensitive tape provides remarkable properties that ensure reliable and efficient performance in various industries. With its premium weight coating of PTFE, #635-6R delivers outstanding release properties, chemical resistance, and a low degree of friction.

The key feature of #635-6R is its strong release properties. The premium weight PTFE coating creates a smooth and non-stick surface, preventing materials from adhering to the tape. This attribute is crucial in applications where clean and easy release is essential, ensuring that products or materials can be separated effortlessly without leaving any residue or causing damage.

Chemical resistance is another notable aspect of #635-6R. The PTFE coating offers excellent resistance to a wide range of chemicals, safeguarding the tape from degradation or deterioration when exposed to corrosive substances. This resistance ensures the longevity and reliability of the tape, making it suitable for use in environments where chemical contact is a concern.

#635-6R exhibits a low degree of friction, which contributes to enhanced operational efficiency. The reduced friction facilitates smooth movement and precise control in applications involving packaging, plastics, roll covering, and uPVC window welding. By minimizing resistance and drag, the tape optimizes production processes and improves the quality of finished products.

To enhance ease of use, #635-6R is accompanied by a yellow dimpled release liner. The release liner not only protects the adhesive surface during storage and handling but also provides a textured surface that enhances grip and handling during tape application. The dimples on the release liner allow for quick and effortless liner removal, ensuring a smooth and uninterrupted working surface for the tape to perform its intended function effectively.

#635-6R finds widespread application in the packaging industry, where it excels in high-temperature environments involving heat sealing and a wide range of packaging materials, including polyethylene, polypropylene, and laminated films. Its strong release properties and resistance to high temperatures ensure consistent and reliable seals, preserving product integrity and freshness.

In the plastics industry, #635-6R is a preferred choice for applications that involve mold release processes. It enables easy and clean demolding of plastic parts, improving production efficiency and reducing the risk of damage to molds. Additionally, the tape can be used in extrusion processes to prevent molten plastic from sticking to surfaces, ensuring smooth and efficient production.

Roll covering applications also benefit from #635-6R, as it provides excellent protection for rollers used in various industries such as printing, paper manufacturing, and textile production. The tape's strong release properties, chemical resistance, and low friction prevent materials from adhering to roller surfaces, minimizing downtime and ensuring high-quality output.

#635-6R is also commonly utilized in uPVC window welding, where it contributes to precise and clean weld seams. Its high-temperature resistance ensures the tape remains intact during the welding process, acting as a barrier against adhesion and facilitating accurate alignment for superior finished windows.
