The development of new technologies for the automotive industry focuses on comfort and the safety of passengers. In addition to electric mobility, automated driving is a crucial building block for the mobility of tomorrow. Closely linked to this development is the increased use of sensors.
With Ultradur RX, BASF has now developed a modified polybutylene terephthalate (PBT) specifically for radar sensor applications in vehicles. Thanks to its good resistance against media such as splash water, oils, or salt, the product offers exceptional protection for sensor housings, BASF says. In addition, according to the manufacturer, the new material shields the sensitive electronics in the housings against interference from electromagnetic waves from other vehicles.
"The different grades of the new Ultradur RX series are products designed for absorption and reduction of interference radiation in the range of 76 to 81 GHz. They offer a high level of protection of the sensitive electronics," explains Dr. Erik Gubbels, an expert at the Performance Materials division at BASF.
Absorption and reflection of interference radiation
With increasing electromagnetic interference issues in road traffic, it is crucial that, for optimum sensor functioning, this noise is absorbed and therefore reduced. This is where Ultradur comes into its own. By suppressing radar radiation interference, a better assignment of the received signals is possible, which at the same time means an improvement in safety. As a functionalized plastic, Ultradur RX is therefore an alternative to metal housings, thus contributing to weight savings and higher vehicle efficiency, the manufacturer says.
