Product information

tesa® 4957

Double-sided PE-foam mounting tape



Product description

tesa® 4957 is a double sided PE foam tape, consisting of a highly conformable closed cell PE-foam backing and a tackified acrylic adhesive. The foam tape offers a highly versatile adhesive for high immediate adhesion on numerous types of substrates and high immediate bonding strength even at low bonding pressure. tesa® 4957 features excellent resistance to water, UV and ageing, making it fully suitable for outdoor use. The double sided foam tape is capable of compensating for different thermal expansions of different materials. tesa® 4957 features excellent cold shock absorption. tesa® 4957 is ideally used for general mounting applications and has been externally certified for furniture mirror mounting. tesa® 4957 has also been tested and approved by the IFT institute for window bar mounting.

Main applications

  • tesa® 4957 is used for general mounting applications
  • The double sided tape is used for POS displays and exhibition sample displays
  • The tape is used for shelf edge labels
  • The PE-foam tape is used for cable channels, window bars and window skirting trims
  • tesa® 4957 is used for decorative glass or mirror elements on furniture
  • The tape can be used for solar module frames
