Exatec introduced new product on "Plastics in Automotive Engineering" congress

On the "Plastics in Automotive Engineering" congress held from March 29 to 30 in Mannheim, Germany, Exatec introduced its new product, Exatec 900el.

At the event Exatec showcased the prototype of an electroluminescent interior light-band in different colors directly integrated into polycarbonate glazing panels. This is made possible by an electroluminescent light band, which is integrated by a special process directly into the perimeter of the transparent polycarbonate car roof. The roof was manufactured using the Exatec 900 technology and the light band applied directly onto a film. The illumination intensity conforms to the legal regulations and does not exceed the allowed level. The new technology Exatec 900el allows drivers and passengers to adjust the brightness of the interior lighting to suite their individual needs.

The electroluminescent light-bands consist of a stack of layers that work, in principle, like a capacitor. Between a front and a rear electrode there is a layer of luminescent pigment, which, together with the encapsulating product, forms the insulating layer (dielectric). When a voltage is applied to one of these electroluminescent cells, the color pigments begin to shine due to the current.

This technology is suitable for compact integration in the vehicle because the large luminous areas are dazzle and shadow-free and do not need to be built into the interior like a normal light.
