ASTM D2116 – Standard Specification for FEP Resin Molding and Extrusion Materials

Description:

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.

Scope

1.1 This specification covers melt processable molding and extrusion materials of FEP resin. This specification does not cover recycled FEP materials. These FEP resins are copolymers of tetrafluoroethylene and hexafluoropropylene or modified FEP resins containing no more than 2 % by weight of other fluoromonomers.

1.2 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.

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