PVDF means polyvinylidene fluoride. It is the polymer obtained by polymerization of vinylidene fluoride (VDF or VF2): CH2=CF2.
Hylar® is Solvay’s PVDF brand for the Coating market, while Solef® is Solvay’s brand known in applications like extrusion, molding, water purification membranes or lithium-ion batteries.
Hylar® PVDF has excellent intrinsic resistance to natural aging and does not require anti-UV additives to resist exposure to direct sunlight. It’s remarkable stability when exposed to solar radiation and weather is demonstrated by both accelerated and multiple-year outdoor weathering studies.
Hylar® PVDF is a self-extinguishing material and offers superior fire resistance according to the various independent tests, such as UL-94, Limiting oxygen index (LOI), and auto-ignition temperature.
