Teflon™ FEP CJ 95
Molding and Extrusion Resin

Product Information
For inventory control purposes, product name may be followedby an X.
Products labeled FEP CJ 95 and FEP CJ 95 X are equivalent,
and all information in this document is applicable to both.

Typical Applications
Insulation and jacket for wire and cable in applications
demanding a high degree of stress crack resistance. Tubes andpiping for general and chemical process industry.

Description
Teflon™ FEP CJ 95 is a melt-processible copolymer oftetrafluoroethylene and hexafluoropropylene, without additives,that meets the requirements of ASTM D 2116 Type I.
It offers the excellent combination of properties characteristic ofTeflon™ fluoroplastic resins: non-aging characteristics, chemicalinertness, exceptional dielectric properties, low flammability,
heat resistance, toughness and flexibility, low coefficient offriction, non-stick characteristics, negligible moisture absorption,and excellent weather resistance. As an intermediate molecularweight resin, Teflon™ FEP CJ 95 offers higher processing speeds
than many FEP grades with similar high level of stress crackresistance.
Stress crack resistance is an important element in establishingend-use performance. Extensive testing of wire and cable
constructions is required for definitive performance evaluation.
Experience shows that the MIT folding endurance or flex life
test, performed on a thin film of resin, has established a goodcorrelation with extensive cable testing. The higher the MIT
flex life, the higher the stress-crack resistance of the resin.
MIT test results should be viewed as a guide to comparative
performance of the various grades of resin. We recommendthat for applications involving repeated thermal and flex cycling,
specific tests on the final cable always should be undertaken.
See also the Chemours bulletin, “Grade Selector for Wire andCable Applications.”

Processing
Teflon™ FEP CJ 95 fluoroplastic resin can be processed byconventional melt extrusion, and by injection, compression,transfer, and blow molding processes. For smooth feeding toextrusion equipment, it is supplied in 3 mm (0.12 in) pellets. The
extruders and molding machines used for Teflon™ FEP CJ 95 should
be constructed of high nickel alloy corrosion-resistant materials
and capable of operating at temperatures up to 400 °C (750 °F).

Safety Precautions
Industrial experience has proven that adequate ventilation, in
properly maintained processing and handling areas, will eliminate
known hazards to personnel. Resin containers should be opened
and used in well-ventilated areas.
Equipment used to process at melt temperatures should beprovided with local exhaust ventilation (LEV) to completely remove
all fumes and vapors from the processing area. In addition, careshould be exercised to avoid the contamination of cigarettes andother forms of smoking tobacco when using fluoroplastic resins.
Before processing any fluoroplastics, read the Material Safety
Data Sheet, available upon request from our Customer ServiceGroup 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
edition of 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).

Food Contact Compliance
Properly processed products made from Teflon™ FEP CJ 95 resin
can qualify for use in contact with food in compliance with FDA
21 CFR 177.1550 and European Regulation (EU) No. 10/2011.
For details and information, please contact your Chemours sales
representative.

Storage and Handling
The properties of Teflon™ FEP CJ 95 resins are not affected bystorage time. Ambient storage conditions should be designed toavoid airborne contamination and water condensation on the resin
when opening and emptying the packaging.

Packaging
Teflon™ FEP CJ 95 is packaged in 25-kg, single layer, plasticbags. For convenient shipment, orders of 1,000-kg pallets arerecommended.
