Anotácia

This specification addresses the physical properties of melt processible molding and extrusion materials of EFEP-fluoropolymer, wherein the EFEP resin is a copolymer of ethylene, tetrafluoroethylene, and hexafluoropropylene. It does not cover blended and recycled materials. Covered here are two types of fluoropolymer that is supplied in pellet form and classified according to their melting points, while the resins of each type are divided into one to two grades in accordance with their melt flow rates. The materials shall be sampled in accordance with an adequate statistical sampling procedure and shall conform to specific gravity, melting point, melt flow rate, elongation, tensile strength, and dielectric constant and dissipation factor requirements when tested by the procedures itemized herein.
