Permeability of Polypropylene WRT Methanol

Permeability of Polypropylene WRT Methanol

Permeability of Polypropylene WRT Methanol

(OP)
I'm trying to find out the transfer rate of methanol through a ~1mm sheet of Polypropylene.  Can any one help?

I've done a fairly extensive search on the web and have good data for HDPE which is a reasonable match I beleive but its PP data that I specifically require.

Thanks for your help

RE: Permeability of Polypropylene WRT Methanol

This book may help: Permeability and Other Film Properties of Plastics and Elastomers 706 pages, ©1995, ISBN 1-884207-14-6, Electronic ISBN:  1-59124-285-1.

It has a section 'Permeability Properties of polypropylene' and also, a table on 'Permeation of Methyl Alcohol.' However, having only the abstract & TOC, I cannot verify it actually has data for methanol permeation through PP.

Another reference to try is Lange's Handbook of Chemistry, but I kind of recall only permeation data for gases & water vapor.
