ASTM D3307-16

Standard Specification for Perfluoroalkoxy (PFA) Resin Molding and Extrusion Materials

ABSTRACT
This specification covers melt processable molding and extrusion materials of PFA-perfluoro(alkoxy alkane) fluorocarbon resin. The materials are copolymers of TFE-fluorocarbon resins containing perfluoroalkoxy side chains. This specification is intended to provide a means for calling out plastic materials used in the fabrication of end items or parts. This specification covers 13 types of PFA-fluorocarbon resins supplied in pellet form for molding and extrusion. The materials shall be of uniform composition and so prepared as to conform to the requirements specified. Conditioning, melt flow rate, melting endotherm peak temperature, specific gravity, tensile properties, and dielectric constant and dissipation factor tests shall be performed to conform with the requirements specified.
SCOPE
1.1 This specification covers melt processable molding and extrusion materials of Perfluoroalkoxy (PFA) resin. The materials are copolymers of tetrafluoroethylene and perfluoroalkoxy.  
1.2 This specification is intended to provide a means for calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection should be made by those having expertise in the plastics field after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this specification.  
1.3 This specification does not cover recycled plastics.  
1.4 The values stated in SI units2 are to be regarded as standard. The values given in parentheses are for information only.  
1.5 The following precautionary caveat pertains only to the test methods portions, Sections 8 and 9 of this specification:  This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Note 1: This specification, ISO 12086–1(2006), and ISO 12086–2(2006) differ in approach or detail. Data obtained using either may not be technically equivalent.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
