tesa® 58334 100µm D/S PET

tesa® 58334 100µm D/S PET

tesa® 58334 is a 100µm differentiated double-sided transparent PET tape equipped with tackified acrylic adhesive.

The tackified acrylic adhesive offers outstanding initial peel strength on polar substrate and fit to rough surface such as mica plate. Its PET backing ensures excellent converting performance. The glassine liner ensures it can be easily released without adhesive residue during application.

Product Features

  • Very fast wetting performance on rough surface, such as mica plate (>1.2N/cm)

  • Outstanding conformability

  • Excellent initial peel strength

  • Good handling performance in converting process

  • Good resistance to demanding automotive environmental conditions

Application Fields

tesa® 58334 has especially been developed for power battery demanding mounting, lamination and converting application with excellent wetting performance on its open side.
Mounting in power battery or lamination application such as:

  • Mica mounting

  • Aerogel mounting

  • other demanding mounting
