In the field of functional tapes, Lohmann‘s engineers have been focusing on advancing bonding technology for the electro-mobility or e-mobility sector. Lohmann is a global innovator in adhesive tape technology.
An average of about 4.5 m² of adhesive tape is used in the majority of automobiles today and, particularly, in electric vehicles.
Functional tapes do more than just connect two objects with one another, according to the company. These adhesive tapes must feature additional properties, including insulation, conductivity, grip, shielding, and others. Functional tapes are in high demand, particularly in the field of electro-mobility.
In this sector, strong bonding is not the only key feature. Thermal and electrical conductivity, as well as shielding or grounding of the components are required (such as for sensors).
Additionally, electronic devices are becoming smaller, even in electric vehicles. In fact, an average of about 4.5 m² of adhesive tape is used in an automobile today. The requirement to fit and bond in tight spaces, however, increases the probability of short circuits or disruption from electromagnetic interference. This is where functional adhesive tapes are the ideal choice because they not only ensure precise bonding of different components, but can also be used for earthing, heat dissipation, or shielding.
Adhesive tapes are also used in the area of sealing to protect the highly sensitive electronic components. Materials are used that can adapt perfectly and seal gaps. These ensure that dust, dirt, and moisture cannot penetrate. In the field of display technology, for example, they also have a damping effect and protect the sensitive technology from impact.
To support these needs, Lohmann’s AS (antistatic) range offers several benefits, including display protection against dust, scratches, and electrostatic discharge. The company’s antistatic films (DuploCOLL AS) help to protect the function of lenses, TFT, and LCD modules, as well as optically bonded touch displays.
When it comes to function and safety — such as for advanced driver assistance systems (ADAS) or highly automated or fully autonomous driving, different issues need to be taken into consideration. Here, electrically conductive (EC) and thermal conductive (TC) tapes work well.
Lohmann’s “Bonding Engineers” have found diverse TC solutions for the application fields of LED, power transistors, heat sinks or PCB heating parts, and more. Another feature manufacturers in the automotive and electronics sector are demanding are silicone-free bonding solutions for parts and components. For this Lohmann has developed its DuploCOLL HCR product range. These adhesive solutions are silicone-free, highly chemical- and temperature-resistant, and resistant to all kinds of environmental influences.
The double-sided PE foam adhesive tape DuploCOLL G, which is equipped with a customized activator, is particularly suitable for the assembly and permanent fixation of mounting parts on large glass surfaces, as are often used in the construction of electric vehicles.
