SABIC announced the expansion of its specialty materials portfolio for advanced driver assistance<br />
systems (ADAS) to further strengthen occupant and pedestrian safety. The company’s two new<br />
LNP STAT-KON compounds are well suited for ADAS radar absorbers and can help propel adoption of<br />
millimeter wave (mmWave) radar, which significantly improves sensor accuracy and range. By providing<br />
robust and high-resolution information about remote objects, mmWave radar could enhance driving<br />
safety and support the trend toward the use of autonomous vehicles.<br />
across mmWave frequencies used for ADAS<br />
radar (76-81 GHz band). By maximizing<br />
noise dissipation, the new compound can<br />
help minimize ghost images and sidelobe<br />
interference, resulting in greater ADAS<br />
radar resolution and accuracy.<br />
The LNP STAT-KON WDF40RI compound<br />
is formulated for metal-backed radar<br />
absorbers. LNP STAT-KON WDF40RI<br />
compound can raise radio wave absorption<br />
to nearly 80 percent, while lowering<br />
reflection below 20 percent, and provide<br />
total shielding when working with metal<br />
backs. Both grades’ noise shielding<br />
performance is consistent across mmWave<br />
frequencies between 75 and 110GHz.<br />
Exceptional Flow Properties Power<br />
New Designs<br />
Incumbent radar absorber materials<br />
typically exhibit high viscosity and<br />
reduced flow stemming from the use of<br />
conductive additives. High viscosity limits<br />
ADAS manufacturers in designing thinwall<br />
internal absorbers or large external<br />
absorbers that surround the radar sensor.<br />
The LNP STAT-KON WDF40RID compound<br />
has an improved flow rate enabling very<br />
thin walls (down to 1mm) for interior<br />
radar absorbers that can reduce side lobe<br />
noise and free up space for additional<br />
electronics. From a processing standpoint,<br />
high flow can sharply reduce scrap from<br />
short shots and increase yield. The<br />
new compound also delivers excellent<br />
dimensional stability at long flow lengths<br />
(up to 20cm). Its low warpage supports the<br />
design of large, curved, exterior absorbers<br />
to reduce noise from adjacent metal parts.<br />
“Our development team applied their<br />
ingenuity and deep technical knowledge to<br />
balance conductivity and flow properties<br />
in our new LNP STAT-KON compounds,<br />
while ensuring exceptional noise diffusion<br />
performance,” said Jenny Wang, Director,<br />
Formulation & Application, APAC,<br />
Specialties, SABIC. “These new products<br />
have addressed key drawbacks of currently<br />
available materials, opening the door to<br />
new internal and external absorber designs<br />
and improved processability. Adoption<br />
of these new compounds can help the<br />
industry advance the state of the art in<br />
ADAS radar.”<br />
Broad Portfolio to Help Advance<br />
ADAS<br />
SABIC offers a growing array of highperformance<br />
materials that may be used<br />
in radar, LiDAR and camera components.<br />
These materials include ULTEM,<br />
NORYL and EXTEM resins and LNP<br />
FARADEX, LNP KONDUIT and LNP<br />
THERMOCOMP compounds. In addition<br />
to radar absorbers, SABIC’s specialty<br />
products have been used for covers and<br />
housings, lenses and lens assemblies,<br />
infrared (IR)-transparent radomes,<br />
electromagnetic shielding plates and<br />
brackets.<br />
