Parker Chomerics Introduces Lightweight, Cost-Effective EMI Shielding
Plastic for Fuel-Conscious Aerospace Applications
WOBURN, MA, October 15, 2007 - Parker, the global leader
in motion and control technologies, through its Chomerics division,
has developed a lightweight, electrically conductive plastic for
EMI shielding of high temperature avionics. PREMIER™ PEI-140
maintains high temperature tolerance, chemical resistance and UL
94V-0 flammability rating for a cost-effective electronics shielding
solution up to 85dB in aerospace applications. PEI-140 complies
with avionics smoke density requirements in the event of an on-board
fire.
According to
Chomerics global product line manager John Perkins, "PREMIER™
PEI-140 is designed to meet the requirements demanded by the avionics
industry. By using PEI-140, avionics systems suppliers can offer
their customers weight reductions to help drive fuel efficiency
and closer tolerance mechanical parts to facilitate tighter fit,
improved sealing and excellent EMI shielding performance."
PolyEtherImide
(PEI) was chosen for the base resin of avionics grade PREMIER for
its outstanding elevated thermal resistance, exceptionally high-strength
mechanical properties, flame resistance and extremely low smoke
generation. PEI-140 is an amorphous thermoplastic reinforced with
matrix of proprietary conductive fillers to provide EMI shielding.
PEI-140 is engineered to optimize stable electrical, mechanical
and physical performance for EMI shielding in continuous use at
temperatures up to 340°F (170°C). PEI-140 is also appropriate
for high performance applications in other industries such as defense,
medical electronics and transportation, where properties of light
weight, strength, flame resistance and EMI shielding add value.
PREMIER PEI-140 provides the only commercially available thermoplastic
system with a homogenous dispersion of the fiber throughout the
molded part, regardless of part geometry. This proven filler morphology,
formulated for consistent shielding up to 85dB over a wide range
of frequencies, combined with proprietary dispersion agent, provides
excellent conductivity and consistent shielding throughout the part.
PEI-140 complies with RoHs, WEEE, EPA, EU and TCO specifications
for ecological compatibility, and contains no halogenated compounds.
Used material may be recycled using standard industry practices.
