tesa ® 4965 is a very strong double sided tape suited to demanding applications, providing a reliable bond to LSE substrates. It that has a modified acrylic adhesive that has a very high temperature range.
The PET backing plastic is strong and performs very well in automated applications (it is not hand tearable).
Available in standard widths from 3mm up to 50mm, non-standard widths available up to 1,300mm.
tesa 4965 Features
- Reliable bond even to LSE substrates (low surface energy)
- Immediate usability right after assembly
- Suitability for most demanding applications such as heavy stress, high temperatures or critical substrates
tesa 4965 Applications
- Mounting of ABS plastic parts in the car industry
- Self-adhesive mounting of rubber/EPDM profiles
- Mounting of decorative profiles and moldings in the furniture industry
- Mounting of battery packs, lenses and touch-screens in electronic devices
