Ultradur® B4300G4 RX1

Ultradur® B4300G4 RX1 by BASF is a tailor-made, modified, polybutylene terephthalate (PBT) reinforced with 20 wt% glass fiber. It is suitable for high-performance radar sensors for automated driving. It exhibits resistance against media such as splash water, oils or salt. This grade absorbs radar waves in the range of 76-81 GHz. It is intended to be used as material to protect radar antennas from electromagnetic noise. The material shows constant protection of sensors against electromagnetic radiation up to atleast 120 GHz. For this grade, ~3 mm is the lowest wall thickness for optimal radar absorption. Ultradur® B4300G4 RX1 reduces signal noise, thus increasing the safety in road traffic. This dielectrically optimized material solution is used in housings and parts with higher mechanical loading. It is used as a rear cover of sensor housing or as an insert behind the print circuit board.
