Recycled Content – ECO-R
► Post-Industrial Recycle (PIR):
Derived from separated industrial waste streams
Generally higher quality due to more defined origin
► Post-Consumer Recycle (PCR):
Derived from separated consumer waste streams
Typically, higher variability and levels of contamination
► Internal scraps:
Derived from internal scraps incl compounded product
Generally, no longer recognized as recycling
Raw materials
Long-term suppliers with proven history and robust systems to
maximize quality, minimize variability and ensure traceability
Finished products
► Compensates performance drop from mechanical recycling step
► Product very close but not identical to prime (no drop in)
► Expanding offer beyond legacy unspecified recycled content to
ECO-R range with specified recycled content

Leading Innovation in E-Mobility Lightweighting & EMI Shielding
HIGH
FLOW
Celanese’s high flow technology enables nominal
wall thickness of 1.0-1.5mm while meeting strict
mechanical, thermal, and emissions requirements.
First 60% long glass-filled polypropylene concentrate
for ultra-thin wall automotive applications. Celanese
offers a broad range of LFT products for EMI shielding
Reduce cycle time, costs, and weight.
Celanese is the only LFRT producer that can supply from 4
continents, and now we have added innovative high-flow
grades to help development of lightweight, thin wall
components.
Celanese materials enable thinner walls, lighter weight, parts consolidation, cost savings and design freedom
across E-mobility segments. An excellent example of weight reduction capability across a broad range of
applications occurs with the use of Celstran® long fiber reinforced thermoplastics (LFRT) for structural and
other larger parts of EV charging Infrastructure.

CoolPoly® E-Series:
Volume resistivity: <100 ohm-cm
Thermal conductivity: 17 – 34 W/m K
Celanese offers one of the broadest portfolios in the industry for thermal management + EMI shielding
► Generic curve for any application with conductive & convective components
► Axes values depends on power input, part size, convective cooling conditions
► Heat transfer is initially conduction limited and later convection limited
► Heat moves through part faster than it can be removed from its surface
CoolPoly® TCP value proposition vs. metals:
► Weight savings due to density difference
► More design freedom with 3D complex geometries
► Part consolidation opportunities
► Reduced fabrication costs & secondary process steps
► Equivalent heat transfer for wide range of designs
