Abstract

This specification covers melt-processible molding and extrusion materials of FEP-fluorocarbon resin, which is a copolymer of tetrafluoroethylene and hexafluoropropylene or a modified FEP-fluorocarbon resin containing not more than 2% by weight of other fluoromonomers. Four types of FEP-fluorocarbon resin are included in this specification which shall be supplied in pellet form and shall be of uniform composition and free of foreign matters. Tests shall be conducted on the molded test specimens wherein the average test result of the lot shall conform to the melt flow rate, specific gravity, melting point, tensile strength, elongation, dielectric constant, and dissipation factor requirements.

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. Scope

1.1 This specification covers melt processable molding and extrusion materials of FEP-fluorocarbon resin. This specification does not cover recycled FEP materials. These FEP resins are copolymers of tetrafluoroethylene and hexafluoropropylene or modified FEP-fluorocarbon resins containing not more than 2 % by weight of other fluoromonomers.

1.2 The values stated in SI units as detailed in are to be regarded as the standard. The values given in parentheses are for information only.

Note 1Although this specification and ISO 12086-1 and ISO 12086-2 differ in approach or detail, data obtained using either are technically equivalent.

1.3 The following precautionary caveat pertains only to the test methods portion, Section 11, 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.
