Polyvinyl Fluoride (PVF)
PVF is a thermoplastic, further classified as a polyvinyl plastic. The graph bars on the material properties cards below compare PVF to: polyvinyl plastics (top), all thermoplastics (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
