tesa® 62508

800µm double sided PE foam tape.

Product Description:

tesa® 62508 is a double sided PE foam tape for mounting applications. It consists of a highly conformable PE foam backing and a tackified acrylic adhesive.

Product features:

High ultimate adhesion level for a reliable bonding performance
Fully outdoor suitable: UV, water and ageing resistant
Conformable PE foam core with high inner strength
Suitable for automatic and manual module assembly
Easy solar module assembly due to a high foam compression rate

Main applications:

Solar module frames
Our goal is to fully understand your application (including the substrates involved) to recommend the right product for the highest possible performance.
