Teflon™ PTFE DISP 30
Fluoroplastic Dispersion

Product Information
Product Description
Teﬂon PTFE DISP 30 is a milky white aqueous PTFE
dispersion stabilized with a non-ionic surfactant. It is a
general-purpose product, often preferred for coating andimpregnating woven goods and for some coating processes.
It imparts properties unique to PTFE resin to porous
structures, as well as to base materials when used as anadditive. When properly processed, the PTFE resin in Teﬂon™
PTFE DISP 30 exhibits the superior properties typical of theﬂuoroplastic resin: retention of properties after service at
260 °C (500 °F) and useful properties at –240 °C (–400 °F).
™

Teﬂon™ PTFE DISP 30 aqueous dispersion provides:• Inertness to nearly all industrial chemicals and solvents• Stability at high temperatures• Excellent dielectric properties• Lowest coefficient of friction of any solid material• Excellent weatherability• Non-stick characteristics

Typical Applications• Coated woven fiber-glass fabric used in architectural, highperformance industrial, food processing, and electronics
applications• Impregnated packing made from braided fibers for severe
chemical and thermal service• Cast film for capacitor dielectrics or chemical barriers

with FDA 21 CFR 177.1550 and European Regulation (EU)No. 10/2011. For details and information, please contact yourChemours representative.

Processing
Conventional dip or ﬂow techniques can be used for coating orimpregnating high temperature fabrics, fibers, and other productswith Teﬂon™ PTFE DISP 30. A continuous PTFE resin coating on
woven fabrics made of fiberglass, Nomex® aramid ﬁber, Kevlar®
aramid ﬁber, or other high temperature-resistant ﬁbers can bemade by dip coating. Multiple passes may be used to build thedesired thickness to produce a smooth, crack-free coating.
Teﬂon™ PTFE DISP 30 is formulated to provide good rewettingon each pass. Each coating layer is usually dried to remove water(typically at 120 °C [250 °F]), baked to remove the wetting agent(typically at 270 °C [518 °F]), sometimes calendered, and ﬁnallyheated above the crystalline melting point of the resin particles(approximately 337 °C [639 °F]).
Products utilizing entrained PTFE resin particles only for theirlubricating or hydrophobic properties are dried and baked, but notheated above the crystalline melting point of the particles. Forexample, rope-like products, such as shaft packings, can be madefrom braided yarn in a variety of cross sections. The dispersion
wets internal surfaces and promotes penetration of the small PTFE
particles. The unmelted particles are sheared and retained as animpregnant, even when compressed in service and exposed tosteam or chemicals. Unmelted particles can also improve ﬂexibility
and ﬂex life in woven fabrics used in hot-gas filtration applications.

• Surface coatings for metallic or other high-temperature
substrates

Other solid or liquid ingredients can be added to Teﬂon™ PTFEDISP 30 to provide speciﬁc processing or ﬁnished productbehavior.

• Anti-drip additive for plastics

Safety Precautions• Binder for battery anode or cathode matrixes

Before processing any fluoroplastics, read the Material 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 thelatest edition of the “Guide to the 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).

Food Contact Compliance
Properly processed products (sintered at high temperaturescommon to the industry) made from Teﬂon™ PTFE DISP 30
resin can qualify for use in contact with food in complianceTeflon™ PTFE DISP 30

Fluoroplastic Dispersion

Storage and HandlingHigh-speed stirring, pumping, or any other violent agitationmust be avoided to minimize sheared particles, coagulation,and foaming. Ideally, the dispersion should be conveyed bygravity from storage to processing stations.

Teﬂon PTFE DISP 30 must be properly stored to maximize
the stability of the dispersion. The PTFE particles will
settle on prolonged standing and/or on prolonged heating—temperatures above 40 °C (104 °F) should be avoided. The
dispersion must be protected from freezing, which will cause
irreversible settling. The optimum storage temperature range
is 7–24 °C (45–75 °F). If dispersions are to be stored forextended periods, lower-temperature storage is desirable.
For optimal performance, Teﬂon™ PTFE DISP 30 should begently mixed or rolled monthly and prior to use.
™

Ammonium hydroxide is used by Chemours to set the pH to
9.5–11.0 at the time of shipment. High ambient temperatures
can deplete the ammonium hydroxide level and reduce pH.
Declining pH eventually favors bacterial growth, which causes
odor and scum. The pH of opened containers should bemeasured and maintained between 9.5 and 11.0.

Storage and handling areas should be clean. Keep dispersion
drums closed and clean to avoid both contamination andcoagulation by drying at the liquid surface. High processing
temperatures will cause even very small foreign particles tobecome visible and/or to make defects in ﬁnished products.
Good housekeeping and careful handling are essential.

PackagingTeﬂon™ PTFE DISP 30 is packaged in 30- and 114-L(8- and 30-gal) non-returnable drums and 1000-L (264-gal)
recyclable containers. Contact the local Chemours salesofﬁce for package sizes available in your speciﬁc geographicarea.
