BRIEFS
SPOTLIGHT: PLASTICS AND COMPOSITES
Rubber ring gear
Vibracoustic
(Darmstadt,
Germany) has
developed a tunable
rubber ring
gear for use in EV
powertrain planetary
gearboxes.
The company
states that the
elastic ring gear
provides superior
vibration isolation
between the
housing and the
ring gear.
Vibracoustic also
claims that its
ring gear mitigates
high-frequency
excitations
such as
torque ripple that often are caused by electric motors and
vibrations that are transmitted into the gearbox housing.
The gear also offers multi-directional decoupling (radial, axial
and torsional) to significantly reduce the transmission of
vibrations. In some applications, this ring gear reportedly
can render additional acoustic encapsulations obsolete
thanks to its wide-frequency working range.

PP Compounds
SABIC (Riyadh, Saudi
Arabia) introduced new PP
compounds for foam injection
molding. New mineral
reinforced SABIC PPc
F9005, PPc F9007 and PPc
F9015 grades reportedly can
help deliver excellent aesthetics
for visible automotive interior parts with complex geometries,
such as door panels and trim, seat and trunk cladding,
A/B/C/D pillar covers and center consoles. The company
claims that total weight loss for these parts could be as
high as 10%. SABIC states that the new PP compound features
uniformly high surface quality similar to solid injection-molded
parts and that foamed parts made with this compound
offer significant weight savings.

Polypropylene and
polyethylene foam
Toray Plastics (North Kingstown, Rhode Island) introduced
its polypropylene and polyethylene foam technologies for
automotive applications. The company's offerings include
ToraSoft, TorayPEF, ToraPRO, and XLPE. The ToraSoft and
ToraPEF foams are intended for luxury haptics in automotive
applications such as instrument panels, consoles, armrests,
glove boxes, seatbacks and knee bolsters. The ToraPRO
foams are specified for flooring applications. Toray states
that these polypropylene-based foams deliver excellent
sound dampening and higher compression resistance at
lower density than traditional polyethylene-based underlayments.
The XLPE foams are used for gasket, tape and composites
applications. These foams reportedly provide end
users with the consistent density, thickness, and uniformity
and are available in a range of densities and thicknesses.

Bluetooth TMPS
Sensata Technologies
(Swindon, United
Kingdom) announced a
new Bluetooth low energy
(BLE) tire-pressure
monitoring system.
Sensata states
that the new BLE TPMS
replaces the ultra-high
frequency (UHF) radio with BLE radio to enable two-way
communication. The system is available in both clamp-in and
snap-in configurations and reportedly features long battery
life while delivering the same pressure, temperature and autolocation
capabilities as Sensata's existing UHF TPMS solutions.
Sensata said it will be launching production of the system
in the first half of 2023.
