gung sowie die Automobilindustrie.

Zu den weiteren am Stand präsentierten

Produkten gehören die auf der patentier-

ten Airquick-Technologie basierenden

Teflon™ Fluorkunststoff-Schaumtypen

(FFR). Datenkabel mit geschäumten Flu-

orkunststoff-Ummantelungen besitzen

eine geringere Signal-Fehlerdämpfung

als herkömmliche Varianten. Dies ermög-

licht Miniaturisierung sowie Gewichts-

einsparung auf Grund der geringeren

Dichte und verringerten Isolationsstär-

ken. Ein aktuelles Beispiel ist das mit ei-

nem DuPont Plunkett Award 2013 aus-

gezeichnete neue Star-Quad-Datenkabel

KL24, das Draka Fileca, Sainte-Geneviè-

ve/Frankreich, für die Luftfahrtindustrie

entwickelt hat. Es ist bei gleichem Durch-

messer bis zu 25 Prozent leichter als bis-

her eingesetzte Quadkabel und ermög-

licht die Reduktion des Treibstoffver-

brauchs von Flugzeugen und damit der

Umweltbelastung.

Broad Portfolio of Teflon™ Resins

for the Wire & Cable Industry

Chemours will be exhibiting its wide

range of fluoroplastics for the wire and

cable industry. Further additions to the

ECCtreme™ ECA family, a class of melt-

processable perfluoroplastics which com-

bines the advantageous mechanical,

electrical and chemical properties of PTFE

with high thermal stability. For instance,

at a thickness of 0.75 mm, the material

has an RTI (Relative Thermal Index) listing

of 300 °C according to UL 746B. Thanks

to its continuous service temperature of

300 °C, ECCtreme™ ECA thus exceeds

the previous upper limit of 260 °C for

conventional perfluoroplastic insulating

materials.

ECCtreme™ ECA grades can be proces-

sed on conventional extrusion equip-

ment for high-temperature fluoroplastics

using standard processing conditions.

as long-term tensile modulus and im-

proved stress cracking resistance.

The material is suitable for wire and ca-

ble insulations, which are exposed to ex-

treme service conditions such as very

high temperatures, elevated pressures

and corrosive surroundings. Typical fields

of application are the oil and gas indus-

try, aerospace, energy generation, semi-

conductor fabrication and the automo-

tive industry.

Further products presented on the stand

will include Teflon™ fluoroplastic foam

resins (FFR) produced using patented Air-

quick technology. Cables made with

foamed fluoroplastic insulation have a

lower signal return loss than conventio-

nal data cables, so enabling miniaturiza-

tion and weight savings thanks to lower

density and thinner insulation thicknes-

ses. One current example is the new

KL24 Star-Quad data cable developed

for the aerospace industry by Draka File-

ca, Sainte-Geneviève, France which won

a DuPont Plunkett Award in 2013. At

identical diameter, it is up to 25 per cent

lighter than previously used quad cables

and enables a reduction in aircraft fuel

consumption, so reducing environmental

impact.
