Your development partner for the future of connected automotive interiors
Are you shaping the future of Human Machine Interfaces (HMI) in the automotive sector and looking for a global partner who can support you with reliable, cost-effective, and contemporary products?
We enable reliable and efficient production processes for next generation Human Machine Interfaces. Regardless of whether you’re dealing with a large curved display, a head-up display, or a smart surface, we offer a variety of adhesive-tape solutions that will allow you to create the interior designs and shapes of the future. Our products are constantly adapted to new OEM requirements and trends. Take a look at the different applications we support.
The connected automotive interior has become the place to differentiate cars. HMIs create a seamless experience between driver and car to share important information for safe driving and to experience new digital services.
Most haptic buttons have already been replaced by displays and seamlessly integrated smart surfaces. Demanding requirements can be met with tesa HMI tapes which enable innovative designs such as complex curved shapes.
tesa's optically clear adhesives (OCA), designed for automotive applications, improve the light transmission, reduce reflection and improve shock absorption as well as stress relaxation. The result is a high quality, easy to read automotive display with sharp images. OCA can be used for various substrates like glass, plastic, or decorative films.
tesa is your preferred partner if you want to further improve your display optical bonding process. We can bring our experienced engineers and partners together to consult you. With OCA tapes a fast and reliable production process is achievable, compared to liquid or hybrid alternatives. Especially when curved, not rectangular or seamlessly integrated displays are designed automotive display assemblers select OCA because of the significantly reduced process complexity and the reduced number of process steps.
tesa® 880xx series
The highlight of the dedicated automotive OCA assortment is the all new 880xx series, which has been specifically developed to integrate displays behind shaped covers made out of automotive polycarbonate grades. The key benefit of this pressure sensitive OCA tape is the superior outgassing prevention function, which enables direct bonding on a coating-less polycarbonate which results in a significant total cost benefit for the display integrator in comparison to the benchmark solutions.
All selected tesa automotive OCA solutions withstand the most crucial automotive test conditions without optical defects or relevant color change.
All tests were performed in a glass/polycarbonate – OCA – polarizer stack up.
The tesa® automotive display mounting solutions are developed to meet the requirements of the next generation of automotive displays such as large and curved shapes and smartphone-like narrow edges and frames. This means that the mechanical load needs to be carried in a continuously smaller area under increasingly demanding environmental conditions. In response, tesa has developed a tape assortment tailored to the automotive safety requirements created out of PE foam and acrylic foam backing technologies.
All selected tesa® automotive display mounting solutions were developed under the following criteria:
With tesa® Bond & Detach we ensure secure bonding over the lifetime of a car and make high-quality electronic components removable and therefore more sustainable. tesa® Bond & Detach is already being used successfully in over 2 billion smart phones. Now tesa® Bond & Detach is available for the automotive market enabling simple and residue free reworking of high value components.
With more and more electrical devices being integrated in cars it is getting more challenging to ensure that the different units do not interfere with each other and additional hand-held devices. To guarantee the functionality of each component, tesa offers a wide range of electrically conductive tapes, enabling grounding and shielding. When developing electrically conductive tapes we can find the right trade-off between adhesive performance such as peel off force and the electrical conductivity for your task. Moreover, we can integrate special electrically conductive foams into the tape stack up, providing additional gap filling features.
With the increasing amount of chips in smaller package spaces, the demand for easy to apply thermal management solutions has also increased. tesa® thermally conductive tapes set up a reliable heat transfer path when mounted between the heat source and heat sink.
To ensure scratch free delivery of display components from supplier to end user, reliable surface protection is important. tesa offers a focus portfolio of transparent protection films that are easy to remove despite automotive typical aging conditions.
All products are not produced under clean room conditions and do not have antistatic treatments. Test conditions for residue free removability after aging and optical properties after aging: 7d at RT, 300h at PV 1200 and ISO 4892-2.
