Standard Specification for Fluorocarbon Perfluoromethoxy (MFA) Resin Molding and Extrusion Materials (Withdrawn 2002)
1.1 This specification covers melt processible molding and extrusion materials that are copolymers of tetrafluoroethylene (TFE) containing perfluoroalkoxy side chains. These side chains are predominately perfluoromethoxy (MFA) chains derived from perfluoro(methyl vinyl ether) and may contain perfluoroalkoxy groups from other perfluoro(vinyl ethers).
1.2 This specification does not cover recycled plastics.
1.3 The tests involved are intended to provide information for identifying the materials covered. It is not the function of this specification to provide engineering data for design purposes. Specimens prepared by injection molding or extrusion could yield test results that may vary from the values in this specification.
1.4 The values stated in SI units, as detailed in IEEE/ASTM SI 10, are to be regarded as the standard. The values given in parentheses are for information only.
1.5 The following safety hazards caveat pertains only to the test methods portion, Section 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-The materials of this specification can be designed and specified according to the system of ISO 12086-1 and the test methods of ISO 12086-2. Details are provided in Appendix X1.
