Features/Benefits: The oriented PTFE film used to make the CHR® 2275-2 adhesive tape is processed to provide high tensile strength and exceptional abrasion resistance while maintaining the superior release properties offered by PTFE. The specially formulated, high-temperature silicone adhesive has excellent adhesion both to the surface to which the tape is being applied as well as to its own backing when wrapped on itself to assure that the tape stays bonded during the application. CHR® 2275-2 removes cleanly after use and is pigmented to facilitate visual inspection during use.

Applications: CHR® 2275-2 is designed to be used as a high-temperature “roller wrap” tape in the production of polyethylene/polypropylene laminates. During this process, the plastic is extruded onto a substrate as it passes through a number of rolls. The tape is wrapped around the rolls to protect the exposed ends of the rollers from the molten plastic, thus preventing build-up of the plastic on the roll surface. The high-temperature capabilities and exceptional durability of 2275-2 enables the tape to be used for long continuous laminating production runs. CHR® 2275-2 can also be used to fabricate belts used in laminating applications as well as other applications that require the temperature and release properties of the tape.
