Vehicle-mounted millimeter-wave radome absorbing materials are functional composite materials used in automotive millimeter-wave radar antenna radomes. They absorb, attenuate, or control the reflection of electromagnetic waves in specific frequency bands (typically 24GHz, 77GHz, and 79GHz millimeter waves), thereby reducing multipath interference, minimizing signal crosstalk, and optimizing radar signal transmittance. These materials are typically composed of a polymer matrix (such as PC, PP, ABS, TPU) and absorbing fillers (such as ferrite, carbon-based materials, conductive polymers, and metal oxides), and are applied to the radome structure through injection molding or coating processes. The core objective is to suppress non-target electromagnetic waves while ensuring structural strength, weather resistance, and wave transmission performance, thereby improving the detection accuracy and stability of ADAS and autonomous driving radar systems.

The upstream of vehicle-mounted millimeter-wave radar radome absorbing materials includes polymer resins (PC, ABS, PP, TPU), microwave-absorbing fillers (ferrites, carbon nanomaterials, carbon black, conductive metal powders), functional additives and masterbatches. Key raw materials include low-dielectric high-frequency resins, nano-scale magnetic particles, conductive fillers and surface modification agents. Representative upstream companies include Covestro, SABIC, BASF, LG Chem, Toray, Cabot, 3M and Hitachi Metals. The midstream consists of radome and absorbing material processors responsible for material compounding, injection molding, electromagnetic tuning and radome structural design. The downstream includes OEM automakers and ADAS suppliers such as Tesla, BMW, Mercedes-Benz, Volkswagen, Toyota, NIO, XPeng, BYD, Bosch, ZF and Denso, where the materials are used in front radar, corner radar and autonomous driving sensing housings.

The vehicle-mounted millimeter-wave radar radome absorbing material market is currently in a growth stage driven by the accelerated penetration of ADAS and autonomous driving systems, and it is one of the more technologically intensive segments in automotive electronic materials. Current demand is mainly driven by the large-scale adoption of front-facing and corner radar systems, while the increasing use of 79GHz high-frequency radar further raises material performance requirements. Key trends include development toward low dielectric constant, high absorption efficiency, wideband response, lightweight design, multilayer composites and integrated injection molding structures, with deeper co-optimization alongside radar antenna design. Key growth drivers include higher levels of driving automation, increasing standardization of ADAS features, stricter vehicle safety regulations and the central role of radar sensing in autonomous driving systems. Major restraints include long material development cycles, complex performance validation, high automotive certification barriers, cost pressure and technological uncertainty from alternative sensing solutions such as LiDAR integration. Overall, future growth will be driven by the upgrade of high-frequency radar systems and broader adoption of autonomous driving technologies.
