Accelerating ADAS adoption with pressure-sensitive tapes
Advanced driver-assist systems (ADAS)
are being integrated into virtually every
type of vehicle, including trucks and offroad
machinery where the safety and
efficiency improvements promised by
these systems are particularly valuable.
However, vehicle manufacturers and their
suppliers frequently face some challenges
when integrating ADAS technology.
Key components of these systems are
often in locations, such as bumpers and
mirrors, where they are exposed to a
variety of environmental factors that can
affect system performance and reliability.
Pressure-sensitive adhesive tapes
can play an important role in not only
mounting ADAS components and bonding
supportive materials, but also in
helping protect them from factors that
degrade performance and cause failure.
Challenges of ADAS integration
Driver-assist technologies rely on a collective
system of cameras, sensors, lidar
and/or radar systems to detect the environment
around the vehicle. The ability
to protect these components from
the factors that impact performance
or cause failures plays a significant role
in how well these systems can deliver
the value users expect. If factors such
as ice buildup, electromagnetic interference
(EMI), dust and vibration corrupt
the information from vision and sensing
technologies, operators will lose confidence
in the systems.
In addressing these challenges, vehicle
manufacturers and their suppliers
For bonding ADAS components to each other and to the vehicle,
manufacturers have three options: liquid adhesives, mechanical fasteners
or pressure-sensitive tapes. The Detroit Assurance safety suite is shown.
also must ensure the materials they use
can support efficient production processes.
For bonding ADAS components
to each other and to the vehicle, manufacturers
have three options: liquid adhesives,
mechanical fasteners or pressure-sensitive
tapes. Liquid adhesives
can form a structural bond with the
substrates used in ADAS technologies,
but these adhesives also can require
longer cure times that can slow and
complicate production processes.
Mechanical fasteners often require special
tools, provide no vibration damping
or other functional protection and can
add to system costs and weight.
Pressure-sensitive tapes provide a
durable and versatile solution for
ADAS mounting and protection applications.
They are easy to apply and
require no time for curing. Engineered
to withstand conditions experienced
by vehicles operating in a range of climates,
their value extends well beyond
their ability to form a strong bond.
Depending on the requirements of the
application, they can provide vibration
damping, thin design profiles and sealing.
Additionally, they can be used as a
bonding solution for materials that
provide gap filling, EMI shielding, light
management and ice mitigation.
ADAS apps for tapes
Pressure-sensitive tapes from leading
manufacturers, such as Avery Dennison
Performance Tapes, are engineered to
make ADAS technologies more durable
and useful through strong bonding with
the substrates used in ADAS components
and by protecting components
from the various factors that can reduce
performance and durability. Here are
some of the applications for tapes in
driver-assist technologies.

bonding tapes are readily
available for bonding PTC heaters to
ADAS components such as cameras,
lidar, radar and ultrasonic sensors.

coated polyethylene (PE) foam and
acrylic foam bonding (AFB) tapes are
used widely in vehicle manufacturing,
including mirror bonding. For ADAS
technologies, these tapes provide a
cost-effective alternative to mechanical
fasteners for mounting, sealing and
damping. Through their application,
manufacturers can ensure reliable
