Teflon™ PTFE 7A X
Granular Fluoroplastic Resin

Product Information
Description

Processing

Teflon PTFE 7A X is a white powder with a small particle
size. Its small particle size helps to minimize voids, even at
relatively low molding pressures. High bulk density increases
the size of moldings possible from a given mold or press
opening. Teflon™ PTFE 7A X is preferred for large moldings
requiring optimum mechanical and electrical properties.
It offers an excellent combination of properties that arecharacteristic of Teflon™ fluoroplastic resins:

Teflon™ PTFE 7A X usually is processed in two steps:
preforming and sintering. The powder is first compacted intoa preformed shape approximating that of the desired molding.
A precise heating (sintering) and cooling cycle is then used toconsolidate the molding at temperatures above the crystalline
melting point of the neat powder. The properties of a finishedmolding are dependent on perform pressure, sintering time
and temperature, and cooling rate. Teflon™ PTFE 7A X isused to make relatively large objects in molds that can befilled manually. Small particle resins do not flow properly in
automatic feeding systems. Refer to the typical property datain Table 1.

™

• Chemical inertness• Exceptional dielectric properties• Heat resistance• Toughness and flexibility• Low coefficient of friction

Food Contact Compliance• Non-stick characteristics

Properly processed products (sintered at high temperaturescommon to the industry) made from Teflon™ PTFE 7A 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.

• Negligible water absorption• Excellent weather resistance
Properly processed products made from neat Teflon™ PTFE
7A X provide the superior properties typical of fluoroplastic
resins. It’s easy to process, handle, and machine.

Typical Applications
Many end products are fabricated from billets, which include
skived film and sheet. It can be used for applications, such as:• Gaskets• Packings• Mechanical seals• Bridge or pipeline bearing pads

• Shaft bearings• Electrical insulators• Piston rings• Expansion bellows• Diaphragms• Chemical linings

The use of fillers provides a wide choice of modified
mechanical properties.

Safety Precautions
Before processing any fluoroplastics, read the Material
Safety Data Sheet, available upon request from ourCustomer Service Group at (844) 773-CHEM/2436 in theU.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).

Storage and Handlingsmall foreign particles to become visible in finished moldings.
Keep resin drums closed and clean. Good housekeeping andcareful handling are essential.

Preforming is easiest when the resin is uniformly between
21–27 °C (70–80 °F). As temperatures decline below thisrange, the resin will be increasingly difficult to mold without
cracks and problems with condensed moisture. Higher
temperatures inhibit flow and promote lumping. Storage
conditions should be set accordingly. Cleanliness is a criticalrequirement for successful use of Teflon™ PTFE 7A X. The
white resin and high sintering temperatures cause evenPackaging
Teflon™ PTFE 7A X is packaged in 40-kg (88-lb) drums. Eachdrum has a bag liner made of polyethylene resin. For shipping
convenience, orders of 320-kg (704-lb) (8 drums/pallet) arerecommended.
