Ultradur® RX for sensor housing

Ultradur RX

People everywhere expect appealing designed, comfortable and safe cars. To meet these requirements, the automotive industry needs continuously innovations. Chemistry is set to play an even greater role in the future as it contributes significantly to solving the mobility challenges ahead. Besides e-mobility, automated driving is gaining importance. The challenges for cameras and sensors with ADAS will continue to increase and play an even greater role

Sensors and cameras are key components to how well a self-driving car performs on the road

With Ultradur® RX BASF has developed a PBT for sensor applications. Like sensitive electronic components, sensors and cameras have to withstand high temperatures on 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. 

Product description and intended usage

  • Ultradur® RX products are tailor-made PBT materials to absorb radar waves in the range of 75-80 GHz 
  • Dielectric optimized material solution to comply with the high standards in sensor industry
  • Intended to be used as material to protect radar antennas from electromagnetic noise 
  • Materials show constant protection of sensors against electromagnetic radiation up to at least 120 GHz
  • Suitable to be used as rear cover of a sensor housing or as an insert behind the printed circuit board (PCB)

Ultradur® RX product portfolio

The absorbing properties vary with material thickness and as such the right material needs to be found for each individual application – the new Ultradur® RX portfolio helps to identify an ideal material match.
