Title: Difference between PVDF & PVF
Post by: Shazaconeda on August 27, 2015, 01:39:54 PM

Hello,

I am trying to find chemical compatibility regarding PVF (Polyvinyl fluoride) specifically.  There is a process that we'll be scrubbing low concentrations of chloroform & HCL vapors.  I'm trying to find out if it holds up to chloroform & HCL, but can't find anything regarding PVF. 

Now, PVDF is great for both & I was hoping that someone might have some evidence, or a good link to verify if PVF & PVDF were similar.  I'm not finding it anywhere.  We'll be using butterfly valves in the process & a manufacturer sells PVF coated wafer valves, but they don't have the ability to check compatibility either.

Thanks!

This reference has some info, see p. 160 and tables:
