Automotive Exports August 2023

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