Kynar® PVDF for filament extrusion

Kynar® PVDF (polyvinylidene fluoride) resins are extremely resistant to harsh chemicals and UV radiation. They are known to be among the most durable polymers in the world. This tough semi-crystalline fluoropolymer, formulated for printability, benefits from outstanding Z-direction strength and ductility. Filaments made from Kynar® resins are particularly suited for early-stage prototyping or short-run manufacturing. Kynar® fluoropolymers are specified for printing chemical processing equipment, fluid transport parts, outdoor exposed elements, or jigs & fixtures.
