A particularly appealing area of use for polybutylene terephthalate (PBT) and polyamide compounds is ADAS radar sensors and their housings. All of a vehicle’s surroundings are monitored by ADAS sensors.
Their use of electromagnetic waves, such as ultrasound, imaging, or laser beams (LiDAR), as well as other electromagnetic phenomena, has a considerable impact on the material selected for the sensor housing. Laser transmission welding is an efficient way to process hydrolysis-stabilised, dimensionally stable, and radar-permeable polymers.
The Global ADAS polymers market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The housings for advanced driver assistance systems can be made of polymers rather than aluminium. Sensitive ADAS circuits can be shielded with specialised polymers, which also allow for more design flexibility and weigh less than aluminium.
It is obvious that basic safety features like lane departure warnings and back-up cameras should be included in advanced driver assistance systems (ADAS). The amount and sophistication of the electronics also increase as technology advances and performance requirements rise.
it can be difficult to safeguard these components with robust housings that won’t significantly add to the vehicle’s total weight, especially if users think that the only alternative is an aluinium housing.
When used as ADAS housings, advanced polymers have advantages over metal in terms of weight reduction and the ability to shield and offer vital static protection for the electronics.
The enhanced design flexibility that new polymers offer also allows you to fit more functionality into smaller places. When compared to aluminium, specialised polymer formulations have a track record of being lighter and more easily processed. To safeguard all ADAS components, they provide the performance users need.
Furthermore, developers have more latitude to build more compact housings that can accommodate more electronics without compromising performance because these materials can be injection moulded.
Due to its strong thermal conductivity, aluminium is frequently used by designers. But because ADAS housing applications are often convection-limited, specially designed thermoplastics can do an amazing job of dispersing heat.
Metals’ extremely high conductivity may be sufficient to prevent heat-related damage. Engineered polymers can be developed to offer superior thermal management, static dissipation, and EMI/RFI shielding capabilities for the ADAS housing at a lighter weight than metal.
