Teflon™ FEP 9819FL
Fluoroplastic Resin

Product Information
For inventory control purposes, product name may be followedby an X.
Products labeled FEP 9819FL and FEP 9819FL X areequivalent, and all information in this document is applicable
to both.

Description
Teflon™ FEP 9819FL is a specialty fluoroplastic resin available
as a loosely compacted fluff.
Teflon™ FEP 9819FL and the other Teflon™ FEP (fluorinatedethylene propylene) copolymer resins combine the processing
ease of conventional thermoplastics with many properties
similar to those of polytetrafluoroethylene (PTFE). They havehigh melt strength and stability at recommended processing
temperatures.
Teflon™ FEP 9819FL is preferred for products that are
not exposed to severe environmental stress in service.
Properly processed products made from neat Teflon™ FEP
9819FL resin provide the superior properties typicalof the fluoroplastic resins: retention of properties after
service at 204 °C (400 °F), useful properties at –240 °C(–400 °F), and excellent dielectric properties and chemical
inertness to nearly all industrial chemicals and solvents.
Table 1 shows typical property data for Teflon™ FEP 9819FL.
Molded products have moderate stiffness and high ultimate
elongation. In a flame, products of Teflon™ FEP 9819FL resistignition and do not promote flame spread. When ignited byflame from other sources, their contribution of heat is verysmall and is added at a slow rate with very little smoke.

Processing
Teflon™ FEP 9819FL requires special processing techniquesand should only be used after consultation with Chemours
technical personnel. Statements, or data, regarding behavior ina flame situation are not intended to reflect hazards presentedby this or any other material when under actual fire conditions.

Applications
Teflon™ FEP 9819FL is only intended for use in special
application processes in consultation with Chemours.

Safety Precautions
Before using Teflon™ FEP 9819FL resin, refer to the Material
Safety Data Sheet and the latest edition of “The Guide tothe Safe Handling of Fluoropolymer Resins,” published by The
Society of the Plastics Industry, Inc. (www.fluoropolymers.org) orby PlasticsEurope (www.plasticseurope.org).
Open and use containers only in well-ventilated areas using local
exhaust ventilation (LEV). Vapors and fumes liberated during
hot processing of Teflon™ FEP 9819FL should be exhausted
completely from the work area. Contamination of tobacco withthese polymers must be avoided. Vapors and fumes liberated
during hot processing that are not properly exhausted, or fromsmoking tobacco or cigarettes contaminated with Teflon™ FEP
9819FL, may cause flu-like symptoms, such as chills, fever,and sore throat. This may not occur until several hours after
exposure and will typically pass within about 24 hours.
Mixtures of Teflon™ fluoroplastic resin with some finely divided
metals, such as magnesium or aluminum, can be flammable or
explosive under some conditions.

Storage and Handling
The properties of Teflon™ FEP 9819FL resin are not affected bystorage time. Ambient storage conditions should be designed
to avoid airborne contamination and water condensation on theresin when it is removed from containers.

Packaging
Teflon™ FEP 9819FL is packaged in 82-kg (180-lb) drums witha polyethylene inner lining.
