DuPont Teflon FEP 9302

DuPont™ Teflon® FEP 9302
Moulding and Extrusion Resin
 
Resin Characteristics
Excellent combination of viscosity and high stress crack resistance.
 
Applications
Extruded or moulded components for the chemical industry. Jackets for wire and cable applications demanding a high degree of stress crack resistance.
 
Product Information
For inventory control purposes product name may be followed by an X.
 
Products labeled FEP 9302 and FEP 9302  X are equivalent and all information in this document is applicable to both.
 
Typical Application
Tubes, piping, linings, bellows, valves and other components for the chemical industry. Jackets for Wire and Cable applications demanding a high degree of stress crack resistance.
 
Description
DuPont Teflon® FEP 9302 is a melt-processible copolymer of tetrafluoroethylene and hexafluoropropylene without additives that meets the requirements of ASTM D 2116 type IV.
 
It offers the excellent combination of properties characteristic of Teflon® fluoroplastic resins: non-ageing characteristics, chemical inertness, exceptional dielectric properties, low flammability, heat resistance, toughness and flexibility, low coefficient of friction, non-stick characteristics, negligible moisture absorption and excellent weather resistance.
 
Teflon® FEP 9302 is used in the chemical industry for applications such as chemical linings, bellows, valve components, pipes and tubing. In demanding Wire and Cable applications, requiring a very high degree of stress crack resistance, it can be used as a material for jacketing.
 
Thanks to its combination of viscosity and stress crack resistance, it can be processed at faster rates and higher extrusion line speeds than many FEP grades with comparable stress crack resistance performance.
 
Stress crack resistance is an important element in establishing end-use performance. Experience shows that the MIT folding endurance or flex life test, performed on a thin film of resin, has established a good correlation 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 recommend that for applications involving repeated thermal and flex cycling, specific tests on the final cable always should be undertaken. See also DuPont’s bulletin “Grade selector for Wire and Cable applications.”
 
Processing
Teflon® FEP 9302 fluoroplastic resin can be processed by conventional melt extrusion and by compression, transfer and blowmoulding processes. For smooth feeding to extrusion equipment it is supplied in 3 mm (0.12”) pellets. The extruders and moulding machines used for Teflon® FEP 9302 should be constructed of high nickel alloy corrosion-resistant materials and be capable of operating at temperatures up to 400 (750).
 
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 be provided with local exhaust ventilation to completely remove all fumes and vapours from the processing area. In addition, care should be exercised to avoid the contamination of cigarettes and other forms of smoking tobacco when using fluoroplastic resins. Before processing any fluoroplastics, read the Material Safety Data Sheet.
 
Food Contact Compliance
Properly processed products made from Teflon® FEP 9302 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 DuPont representative.
 
Storage and Handling
The properties of Teflon® FEP 9302 resins are not affected by storage time. Ambient storage conditions should be designed to avoid airborne contamination and water condensation on the resin opening and emptying  the packaging.
 
Packaging
Teflon® FEP 9302 is packaged in 25 kg, single layer, plastic bags. For convenient shipment, orders of 1000  kg pallets are recommended.

1) ASTM method unless otherwise specified
2) Definition of continuous service temperature: The continuous service temperature is based on accelerated heat-aging tests, and represents the temperature at which tensile strength and ultimate elongation retains 50% of the original values, after 20 000 h thermal aging When considering the use of Teflon® FEP at elevated temperatures especially in combination with mechanical, electrical or chemical exposure, preliminary testing should be done to verify suitability.
3) These results are based on laboratory tests, under controlled conditions, and do not reflect performance under actual fire conditions.
