tesa® ACXplus 70200 Certified Durability

2,00 µm double-sided acrylic foam tape



Product description

tesa® ACXplus 70200 is a deep black viscoelastic acrylic foam tape. It consists of a high-performance acrylic core, which compensates different thermal elongation of bonded parts. Due to its unique components, it combines a very good temperature resistance with an outstanding cold shock resistance up to -40°C.


Main applications

tesa® ACXplus 70200  can act as primary bonding system for different Building Envelope components. It is designed to resist wind loads, temperature changes leading to thermal expansion, and continuous transfer of the forces to the substructure over many years. tesa® ACXplus  7200 can outperform conventional fastening methods by optimizing our customers’ production processes and the quality and aesthetics of their products.

The main applications are:
  • Bonding carrier profiles to aluminum composite material (ACM)
  • Fixing glass to the structural glazing frame
  • Mounting reinforcement bars into façade cassette systems

Additional Info

  • tesa® has developed a structured process on evaluating Building Envelope projects
  • tesa® ACXplus 70200 may only be used after detailed examination including individual adhesion tests. A written approval of the corresponding project details is given  by tesa®’s structural design laboratory.
  • For wind loads (dynamic tensile or shear loads), a design factor of 90kPa is used for tesa® ACXplus 70200. This design factor provides an industry appropriate safety component and was established based on long term material property testing. A dynamic load calculation has to define the minimum tape width for each panel size. This is essential to support the transfer of wind loads to the building structure.
  • For the calculation of static loads a design factor of 1.7kPa is used for tesa® ACXplus 70200. This can be translated into 60cm2 of ACXplus 70200 per 1kg weight to support static loads.
  • tesa® ACXplus 70200  can compensate the shear movement of such materials caused by thermal elongation and contraction, up to three times its product thickness. The maximum shear strain the tape can compensate is 300%. A calculation must determine if the respective material movement causes less strain on the tape than 300%.
