Polyvinylidene Fluoride PVDF Kynar

Polyvinylidene fluoride (PVDF) (Kynar) has the following repeating unit ... [Pg.154]

Polytetrafluoroethylene (PTFE Teflon) was discovered accidently by PlunkettCZ nd commercialized by DuPont in the 1940 s. This polymer has a solubility parameter of about 6H and a high melting point of 327°C and is not readily moldable. Poly-chlorotrifluoroethylene (CTFE, Kel-F), the copolymer of tetrafluoroethylene and hexafluoropropylene (FEP), polyvinylidene fluoride (PVDF, Kynar), the copolymer of tetrafluoroethylene and ethylene (ETFE), the copolymer of vinylidene fluoride and hexafluoroisobutylene (CM-1), perfluoroalkoxyethylene (PFA) and polyvinyl fluoride (PVF, Tedlar) are all more readily processed than PTFE. However, the lubricity and chemical resistance of these fluoropolymers is less than that of PTFE. [Pg.92]

Polyvinylidene fluoride (PVDF) (PVF2) is made from 1,1-difluoroethylene by polymerization in bulk, solution or dispersion with starters such as peroxides or y-radiation. Commercial PVDF products are Kynar (Pennwalt Corporation), Sole (Solvay) and Vidar (AWK Trostbergj [2]. [Pg.24]

Polyvinylidene fluoride (Kynar) (PVDF) is probably the most widely used fluorinated polymer for chemical applications. It can be melt-processed using virtually all the melt-processible procedures. PVDF components such as pipe fittings, tubing, sheet, shapes, and... [Pg.37]
