Anotácia textu normy ASTM D3222-21(2026) :
This specification covers melt processable unmodified poly(vinylidene fluoride) (PVDF) molding, extrusion and coating materials. This specification covers only virgin homopolymer prepared from vinylidene fluoride supplied in form of pellet or powder and shall be free of foreign matter. Two types covered by this specification are type I PVDF fluoroplastics and type II PVDF fluoroplastics. Detailed requirements that shall conform to this specification include peak melting endotherm, specific gravity, refractive index, limiting oxygen index, flow rate, rheological properties, tensile properties, flexural properties, impact resistance, D-C resistance, dielectric strength, dielectric constant, and dissipation factor. Preparation of compression molded specimen shall be in accordance to this specification.
