tesa® 4957

Double-sided general purpose PE-foam tape

Product description

tesa® 4957 is a double-sided tape consisting of a very conformable closed cell PE-foam backing and a shear resistant modified acrylic adhesive. It is fully suitable for outdoor use and is available in black and white.

tesa® 4957 features especially:
  • High immediate bonding strength on rough surfaces
  • Very good compensation for design tolerances
  • Leveling out different thermal elongation of materials
  • Shock absorption and sealing function

Application Fields

  • POS displays, exhibition sample displays
  • Shelf edge labels
  • Cable channels, window and kitchen profiles
  • Decorative glass or mirror elements on furniture
  • Signs & Emblems
