Product information

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 benefits:
  • 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
  • Mounting of trims and profiles
  • General mounting applications

Additional Info

Liner variants:
  • PV0 brown glassine paper (71 µm)
  • PV13 transparent PET film (50 µm)
  • PV15 blue PE film (100 µm)

Peel Adhesion:
  • immediately: foam splitting on steel
  • after 14 days: foam splitting on steel, ABS, Aluminium, PC, PET, PS, PVC

tesa® 62508 is recognized by UL as photovoltaic polymeric material (QIHE2).

tesa® 62508 has been tested by TÜV Rheinland, Germany. The test confirms the longterm adhesion performance after IEC 61215 climate tests and a 85°C temperature resistance.

The temperature resistance (short/long) of tesa® 62508 has been approved according to tesa test method under static load.
