Teflon™ PTFE 6CN X
Fine Powder Fluoroplastic Resin

Product Information
DescriptionProcessing

Teflon PTFE 6CN X is a polytetrafluoroethylene fine powder
resin used primarily for paste extrusion. Teflon™ PTFE 6CN X
offers the excellent combination of properties typical of
Teflon™ fluoroplastic resins:

Teflon™ PTFE 6CN X is extruded using a liquid processing aid
such as naphtha. In the paste extrusion process, the powder
is mixed with a lubricant aid and then compressed into acylindrical preform slug under light pressure (1.5–2.0 MPa[220–290 psi]). The preform slug is placed in the cylinder ofa paste extruder, where the composition is forced under highpressure through a finishing die to produce beading, tubing, orwire coatings.

™

• Non-aging characteristics• Chemical inertness to nearly all industrial chemicals andsolvents• Exceptional dielectric properties, stable with frequency
and temperature• Toughness and flexibility• Low coefficient of friction• Non-stick characteristics• Negligible moisture absorption• Excellent weather resistance• Service temperature up to 260 °C (500 °F)• Useful properties at –240 °C (–400 °F)

After extrusion, the product is a low-density, but coherent,fibrous structure. Teflon™ PTFE 6CN X is usually processed
further, with heat, into a solid resin product such as tubing.
Heat is applied in two steps, which may be taken in-line withextrusion or separately. The lubricant must be removed first,usually by heating within the range of 100–300 °C (212–572 °F). A sintering step follows to melt the resin above its
melting point of approximately 342 °C (648 °F) and produce
the void-free, solid PTFE resin.

• Moderate stiffness and high ultimate elongation

Food Contact Compliance

Teflon™ PTFE 6CN X is designed for processing at medium
to high reduction ratios of 250:1 to 2000:1. It is particularly
suitable for production of wire coating, jacketing, and tubing
at fast sintering rates.

Properly processed products (sintered at high temperaturescommon to the industry) made from Teflon™ PTFE 6CN X
resin can qualify for use in contact with food in compliancewith FDA 21 CFR 177.1550 and European Regulation (EU)No. 10/2011. For details and information, please contact
your Chemours sales representative.

Teflon™ PTFE 6CN X meets the requirements of ASTM
D4895, Type I, Grade 2, Class C.

Typical Applications
Teflon™ PTFE 6CN X is mainly used for wire and cableinsulation and tubes with thin wall tubing, such as
spaghetti tubing.

Safety Precautions
Before processing any fluoroplastics, read the Safety
Data Sheet, available upon request from our Customer
Service Group at (844) 773-CHEM/2436 in the U.S.
or (302) 773-1000 outside of the U.S. Also read thedetailed information in the latest edition of the “Guide tothe Safe Handling of Fluoropolymer Resins,” published by
the Fluoropolymers Division of The Society of the Plastics
Industry (www.fluoropolymers.org) or by PlasticsEurope(www.plasticseurope.org).

Fine Powder Fluoroplastic Resin

Storage and Handling

may be used; however, harder lumps that can not be broken
up should be discarded.

Teflon™ PTFE fine powder resins must be handled carefully toavoid shearing the powder prior to extrusion. Fibrillation by
shearing is not reversible, and damaged particles can appear
as defects in the finished product. As temperature is reduced
below the transition point of 19 °C (66 °F), the powder
becomes progressively less sensitive to mechanical damage
or compaction in its containers.
Chemours recommends that powder compacted during
shipping and storage be restored to its optimum condition bycooling it for one or two days below 19 °C (66 °F), followedby screening through a 2 to 4.76 mm opening sieve (4 to10 mesh). Lumps that are retained on the sieve that can be
broken up by shaking at temperatures below 19 °C (66 °F)

All processing steps prior to preforming should be done at
reduced temperature, but ambient dew point must be controlled
to prevent condensation on the resin. Storage and handlingfacilities should be clean to avoid any cross-contamination.
The high sintering temperature causes even very small foreign
particles to become visible or to cause defects in finishedproducts. Keep resin drums closed and clean.

Packaging
Teflon™ PTFE 6CN X resin is packaged in 25-kg (55.1-lb)
plastic containers. For convenient shipment, orders of
300-kg (661.4-lb) pallets (12 drums) are recommended.
