About PVDF:

 

PVDF is a kind of engineering plastic,with half transparent or white powder or frain appearance.The Molecular chain is very close,own doughty hydrogen bond,it contain 46% oxygen,flammability resistance,with 65%-78%rime degree,density is1.17-1.79g/cm^3, melting point is 172°C,heat distortion temperature is 112-145°C,long-term work temperature is 140-150°C.PVDF has the property of flurin resin and other general resin,except good chemical resistance,heat resistance,oxidation resistance,climate resistance,radial resistance,it also has piezoelectricity property,dielectric property and so on.
