This specification covers melt processible molding and extrusion materials of modified ETFE-fluoropolymer. The ETFE resin is a copolymer of ethylene containing approximately 75 mass% of tetrafluoroethylene. This specification addresses virgin materials only as performance requirements cannot be met with recycled material. Modified ETFE-fluoropolymers shall be supplied in pellet form and classified into five types according to their specific gravity. Furthermore, the resins of each type are divided into three grades according to their melt flow rate. Materials shall be sampled, prepared, and conditioned as appropriate for testing, wherein the following performance requirements must be met: melting point and flow rate; melting endotherm peak temperature; specific gravity; tensile properties (tensile strength and elongation); and dielectric constant and dissipation factor.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers molding and extrusion materials of modified ETFE fluoropolymer. The ETFE resin is a copolymer of ethylene and tetrafluoroethylene. Modified ETFE resin contains no more than 5 mole % of other fluoromonomers.
1.2 The values stated in SI units as detailed in are to be regarded as standard. The values given in parentheses are for information only.
Note 1: Although this specification and ISO 20568-1 and ISO 20568-2 differ in approach or detail, data obtained using either are technically equivalent.
1.3 The following safety hazards caveat pertains only to the test method portion, Section 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. , of this specification.
1.4 Recycled material is not appropriate for this specification because performance requirements cannot be met with recycled material. Therefore, this specification is for virgin material only.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
