Cytec Carbon Fibers
ThermalGraph®Fabric
EWC-300X
ThermalGraph Fabric is a pitch-based, high thermal conductivity
woven fabric developed for thermal management applications.
Due to the orthotropic nature of the weave, and the
high longitudinal thermal conductivity of the fibers,
biaxial thermal conductivity is achieved. Through-the-thickness
thermal conductivity is enhanced by the weaving crimp.
This product is easily prepregged and processed into
a composite form. EWC-300X is available as a plain
weave fabric constructed from 4000 (4K) filament continuous
pitch tows and as an eight harness satin fabric constructed
from 2000 (2K) filament continuous pitch tows.
