Versatile E&E applications for the automotive
From fuse boxes to modern power electronics - there is hardly an electrical application that does not rely on plastics. Where electricity flows, our Engineering Plastics and Polyurethanes show outstanding electrical as well as good mechanical properties and a high dimensional stability under heat.

Sensors
Like sensitive electronic components, sensors have to withstand high temperatures in all climate zones worldwide. Besides eMobility, automated driving is gaining importance and sensors are key components for the performance. As sensors are asked to play a greater role, the challenges for these sensors in ADAS will continue to increase. Tailor-made Engineering Plastics, like Ultradur® RX, are resistant to media like spray water, oils or road salt while they are able to block or transmit radar waves from other vehicles.

Control units
The electronic control unit housings have to protect the sensitive automotive electronics and have to be functional in all climate zones on earth. This includes hot damp conditions, spray water and road salt which increases the requirements on the plastic. Therefore, the level and duration of the stress are key factors as to whether or not an application is feasible. Ultradur® HR is the ideal choice for performance in challenging environments.

Motors and actuators
With the increasing use of actuators, such as in seat control, automatic light controlling or door locks, the comfort for the driver is also growing. Due to miniaturization and functionalization of components, actuators are becoming smaller and more complex, which demands a high mechanical performance of materials such as Ultraform®, Ultradur® or Ultramid® Advanced from BASF. They convince with high dimensional stability, wear resistance and are optimized for complex components in actuators.

Cable Management
Speed sensor cables for ABS and ESP systems use outer-sheathings of Elastollan® to provide a secure flow of information – even in the area of the wheel house, close to the axle, which is at risk of impact from stones and exposure to water, vibration and low temperatures. BASF thermoplastic polyurethane is also used for charging cables as flame retardant material.
A cable harness is typically limp and has to be transformed into a specific, three-dimensional, pre-formed geometry using aids – for example cable conduits or tape. With Elastofoam®, the foaming of the application gives more flexibility, provides mechanical protection and the integration of mounting elements is possible.

High-voltage connectors
High-voltage connectors can be most often identified by their typical orange color. The light-colorable Ultradur® is color stable and resistant to thermal aging. The color coding of the individual components is safety-relevant: It needs to remain highly visible for at least ten years. While being part of the non-halogenated flame-retardant portfolio, the BASF polybutylene terephthalate (PBT) as well offers high hydrolytic resistance and excellent electrical insulation (CTI 600).

![With Ultradur® RX, BASF has now developed a modified polybutylene terephthalate (PBT) specifically for radar sensor applications in vehicles. The different product grades of the new Ultradur® RX series are materials designed for absorption and reduction of interference radiation in the range of 76 to 81 GHz. Thanks to its good resistance against media such as splash water, oils or salt, Ultradur® offers an exceptional protection for sensor housings. In addition, the new material shields the sensitive electronics in the housings against disturbing electromagnetic waves from other vehicles.
