Typical Applications


Applications for Everflon™ PFA GC430 include high performance thinwall wire coatings; intricate injection molded parts for production of chemicals where purity in the parts-per-billion range is needed; semiconductor components and electronic parts; and fluid handling systems for high performance chemical filters. With a typical melt flow rate (MFR) of 35, Everflon™ PFA GC430 resin is ideally suited for applications requiring a high processing speed and very low viscosity.
 
 

Processing Guide


Everflon™ PFA GC420 can be processed by conventional melt extrusion, and by injection, compression, and transfer molding processes. High melt strength and heat stability permit the use of relatively large die openings and high temperature draw-down techniques that increase production rates. Reciprocating screw injection molding machines are preferred.
Corrosion-resistant metals should be used in contact with molten fluoroplastic resin. Extruder barrel should be long, relative to diameter, to provide residence time for heating the resin to approximately 390 °C (730 °F)
 

Precaution


Equipment used to process at melt temperatures should be provided with local exhaust ventilation (LEV) to completely remove all fumes and vapors 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.
 

Package and Handling


The properties of Everflon™ PFA resin are not affected by storage time. Ambient storage conditions should be designed to avoid airborne contamination and water condensation on the resin when it is removed from containers.
Everflon™ PFA is supplied as pellets and is available in 25-kg multilayer bags with an integral polyethylene liner.
 
 

Food Contact Compliance


Properly processed products made from Everflon™ PFA GC430 resin can qualify for use in contact with food in compliance with FDA 21 CFR177.1550 and European Regulation (EU) No. 10/2011.
