Solutions for the Consumer Electronics Industry

Product description

tesa® HAF 8451 is a thermosetting film based on phenolic resin and nitrile rubber, especially designed for applications that require high resistance against shock, e.g. in case of dropping. This double-sided tape has no backing. It is protected by a strong paper liner.

At room temperature tesa® HAF 8451 is not tacky. It is activated by heat and pressure during defined intervals.

tesa® HAF 8451 enables extremely strong and age-resistant bonds between different materials, even on porous surfaces.

tesa® HAF 8451 features:

  • Excellent shock resistance, particularly under cold conditions
  • Excellent conformability for porous or curved substrate surfaces, including 3D surfaces
  • Reliable and age-resistant bonds between plastic and metal surfaces, even on very small bonding areas
  • Suitable for long-term applications that are exposed to heavy stress, especially at low temperatures
  • Bonds remain elastic even at very low temperatures

Main applications

It is especially recommended for bonding of metal components to various plastic or metal surfaces, e.g. Aluminium and PC and ABS.

  • Bonding of nameplates for mobile phones
  • Bonding of frame to PDA-housings
