#635-3R (with release liner) is a 3mil high-quality PTFE coated fiberglass tape with a strong silicone adhesive, making it an ideal choice for various industries that require reliable performance in high-temperature environments. The tape's premium weight coating of PTFE offers excellent release properties, chemical resistance, and a low degree of friction, making it suitable for use in a range of applications.

One significant advantage of #635-3R is its ability to withstand high temperatures, making it a popular choice in the packaging industry for heat-sealing and vacuum packaging applications. The tape's strong release properties and chemical resistance ensure that it can withstand harsh packaging environments without degrading or losing its performance.

In the plastics industry, #635-3R is often used for mold release applications, where it helps prevent sticking and enables easy removal of molded plastic parts. The tape's low coefficient of friction also makes it a suitable choice for roll covering applications in the paper and textile industries, where it can help reduce wear and tear on machinery.

#635-3R is also commonly used in the construction industry for uPVC window welding applications, where it serves as a release liner. The tape's PTFE coating provides a smooth, non-stick surface that prevents the welding material from sticking to the tape, ensuring a clean and efficient welding process.

This item is also available without a release liner (#635-3), making it easier to handle and apply, particularly in automated applications. The release liner also protects the tape's adhesive from contamination and maintains its performance until it is ready to be applied.

#635-5 is a versatile, high-performance tape that offers excellent release properties, chemical resistance, and a low degree of friction. Its suitability for use in high-temperature environments makes it an ideal choice for various industries, including packaging, plastics, roll covering, and uPVC window welding.
