People everywhere expect appealing designed, comfortable and safe cars. To meet these requirements, the automotive industry continuously needs innovations. Chemistry is set to play an even greater role in the future as it contributes significantly to solving the mobility challenges ahead. Besides eMobility, automated driving is gaining importance. The challenges for cameras and sensors in ADAS will continue to increase just when sensors will play a greater role.
Sensors are key components for the performance of self-driving cars
With Ultradur® RX, BASF has developed a PBT for sensor applications. Like sensitive electronic components, sensors have to withstand high temperatures in all climate zones worldwide. They have to be resistant to media like spray water, oils or road salt while they have to block or transmit radar waves from other vehicles.
