Teflon™ PTFE 601 X
Fine Powder Fluoroplastic Resin

Product Information
DescriptionProcessing

Teflon PTFE 601 X is a polytetrafluoroethylene fine powder
resin used primarily for paste extrusion. Teflon™ PTFE 601 X
offers the excellent combination of properties typical of
Teflon™ fluoroplastic resins:

Teflon™ PTFE 601 X is extruded using a liquid processing
aid, such as naphtha. In the paste extrusion process, thepowder is mixed with a lubricant aid and then compressed
into a cylindrical preform slug under light pressure(1.5–2.0 MPa [220–290 psi]). The preform slug is placed in
the cylinder of a paste extruder, where the composition isforced under high pressure through a finishing die to produce
beading, tubing, or wire coatings.

™

• Chemical inertness to nearly all industrial chemicals andsolvents• Superior in-use thermal stability (low thermalinstability index)• Exceptional dielectric properties, stable withfrequency 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)• Moderate stiffness and high ultimate elongation
Teflon™ PTFE 601 X is designed for processing at low tomedium reduction ratios of 10:1 to 300:1. It is particularly
suitable for unsintered stretched products and for sinteredproducts with high mechanical properties.
Teflon™ PTFE 601 X meets the requirements of ASTM
D4895, Type I, Grade 1, Class A.

Typical Applications
Teflon™ PTFE 601 X is mainly used for unsintered articles,
including filter membranes and gaskets.

After extrusion, the product is a low-density, but coherent,
fibrous structure. After removal of the lubricant by heating
within the range of 100–300 °C (212–572 °F), theextrudate can be either sintered above its melting pointof around 345 °C (653 °F) to produce a void-free PTFE
article or calendered and stretched to produce unsintered orsemi-sintered articles.

Food Contact Compliance
Properly processed products (sintered at high temperaturescommon to the industry) made from Teflon™ PTFE 601 X resin
can qualify for use in contact with food in compliance withFDA 21 CFR 177.1550 and European Regulation (EU) No.
10/2011. For details and information, please contact yourChemours sales representative.

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

All processing steps prior to preforming should be doneat reduced temperature, but ambient dew point must becontrolled to prevent condensation on the resin. Storage
and handling facilities should be clean to avoid any crosscontamination. The high sintering temperature causes evenvery small foreign particles to become visible or to cause
defects in finished products. Keep resin drums closedand clean.

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 orcompaction in its containers.
Chemours recommends that powder compacted during shippingand storage be restored to its optimum condition by cooling it
for one or two days below 19 °C (66 °F), followed by screening
through a 2 to 4.76 mm opening sieve (4 to 10 mesh). Lumps
that are retained on the sieve that can be broken up by shaking
at temperatures below 19 °C (66 °F) may be used; however,
harder lumps that cannot be broken up should be discarded.

PackagingTeflon™ PTFE 601 X resin is packaged in 27.2-kg (60-lb)
plastic containers. For convenient shipment, orders in
multiples of 326.4-kg (720-lb) pallets (12 drums) arerecommended.
