REDUCING ADAS ALIGNMENT ISSUES WITH SABIC'S LOW WARPAGE MATERIALS
Various factors can le d to alignment issues in radar rear housings or brackets, such as accidents and even part warpage. SABIC's LNP™ THERMOCOMP™ compounds can decrease warpage versus a standard glass filled PBT by up to 58% throughout the molding process.
Recalibrating sensor systems can result in increased repair costs, according to a AAA article (ADAS Sensor Calibration Increases Repair Costs I AAA Automotive). AAA states: "Most ADAS sensors are very precisely aimed and require calibration if their positions Thermal are disturbed in any way. Consider Camera that a sensor on the car that is out of alignment by a fraction of an inch or even one degree will be aimed at an area significantly off axis 50 or more feet down the road". Materials offering low warpage could be critical in end design and hardware functionality.
WARPAGE COMPARISON: GF PBT VS. LNP™ THERMOCOMP™ COMPOUND
Low warpage benefit: Molding with SABIC's LNP™ THERMOCOMP™ compounds can reduce part warpage by 58% up to vs standard glass filled PBT.
Along with the excellent low warp benefits, LNP™ THERMOCOMP™ compounds surpass incumbent PBT compounds in Df/Dk performance and can help reduce attenuation of electro-magnetic waves passing through the radar covers to help improve image resolution and range. They can also help enhance transmission and minimize side cones of the signal beam for improved image quality. In addition, the new LNP™ THERMOCOMP™ compounds provide higher ductility for improved impact resistance, and equivalent moisture and chemical resistance vs. incumbent PBT materials.
