BumperFlex is a highly resilient flexible polyurethane based tape coated with an aggressive pressure sensitive adhesive. This tough, yet durable material is ideal for preventing squeaks & rattles. It also offers protection against scratches and is the perfect way to create a non-slip base over a large area due to it’s high coefficient of friction.
BumperFlex protective tapes are supplied on a roll with a thick backing paper suitable for die-cutting into roll form for automated applications. A BumperFlex feature is that it’s easily
die cut into pads, discs, washers, gaskets or squares to suit almost any job.

Applying BumperFlex
It is important to remember, that as with any self adhesive product, the surface to which they are being applied must be clean, dry and free from dust and dirt. Therefore, to gain maximum adhesion, clean the surface with low strength solvent and allow to dry thoroughly before use. Please follow solvent manufacturers’ instructions for safety. The information provided above have been gained under laboratory conditions. It is important customers test BumperFlex themselves to ensure suitability for intended applications.
All BumperFlex tapes are RoHS and Wee compliant.
