ASTM | Standard Specification for Extruded and Compression Molded Shapes Made from Poly(Vinylidene Fluoride) (PVDF)
This specification covers the requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded sheet, rod and tubular bar manufactured from Poly(Vinylidene Fluoride) (PVDF). The type of PVDF shape product may be categorized by type, grade and class depending on resin and filler compositions. Each type of shape may be categorized into one of several grades as follows: Grade 1 - unmodified virgin-extruded or compression molded product made using only 100 % virgin PVDF material; Grade 2 - general purpose-extruded or compression molded product made using up to 20 % PVDF regrind developed during internal processing steps may be used; and Grade 3 - recycled-extruded or compression molded product made using up to 100 % recycled PVDF resin.
