Teflon™ PTFE 62XT X
Fine Powder Fluoroplastic Resin

Product Information
Description
Teflon PTFE 62XT X is a polytetrafluoroethylene fine
powder resin used primarily for paste extrusion. Teflon™ PTFE
62XT X offers the excellent combination of properties typicalof Teflon™ fluoroplastic resins:™

• 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)• Moderate stiffness and high ultimate elongation
Compared with other grades of PTFE fine powder, Teflon™
PTFE 62XT X is a premium resin that has increased thermalstability, superior flex life, superior stress crack resistance,
low permeability, and high clarity.
Teflon™ PTFE 62XT X is designed for processing at medium
to high reduction ratios of 400:1 to 1600:1. It is particularly
suitable for production of high quality tubing, spaghettitubing, and wire coating. This grade is also highly suitable
for after-processing technologies, such as flanging, welding,blow molding, and convoluting.
Teflon™ PTFE 62XT X meets the requirements of ASTM
D4895, Type 1, Grade 3, Class D.

Typical Applications
Teflon™ PTFE 62XT X is used primarily in the productionof tubing installed in applications requiring the ultimate

in reliability and performance. Applications are found in thechemical, pharmaceutical, and automotive industries wherecontact with hydraulic fluid, hydrocarbon fuel, or reactive gases
is required. One such application is high pressure tubing in heatexchangers.

Processing
Teflon™ PTFE 62XT X is extruded using a liquid processing aid,such as naphtha. In the paste extrusion process, the powder ismixed with a lubricant aid and then compressed into a cylindricalpreform 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 is forced under high pressure through afinishing die to produce beading, tubing, or wire coatings.
After extrusion, the product is a low-density, but coherent, fibrous
structure. Teflon™ PTFE 62XT X is usually processed further, withheat, into a solid resin product, such as tubing. Heat is applied intwo steps, which may be taken in-line with extrusion or separately.
The lubricant must be removed first, usually by heating within therange of 100–300 °C (212–572 °F). A sintering step follows tomelt the resin above its melting point of approximately 342 °C(648 °F) and produce the void-free, solid PTFE resin.

Food Contact Compliance
Properly processed products (sintered at high temperaturescommon to the industry) made from Teflon™ PTFE 62XT X resin
can qualify for use in contact with food in compliance with FDA
21 CFR 177.1550 and European Regulation (EU) No. 10/2011.

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 the detailed information in the latest editionof the “Guide to the Safe Handling of Fluoropolymer Resins,”
published by the Fluoropolymers Division of The Society of thePlastics 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 causedefects in finished products. Keep resin drums closed
and clean.

Teflon™ PTFE fine powder resins must be handled carefully to
avoid 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 can not be broken up should be discarded.

Packaging
Teflon™ PTFE 62XT 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.
