I'm looking at gas permeable materials. The unit is in Barrer unit. Is the bigger the number of more permeable or the smaller the more permeable?
And does anybody know where to fund cheap Teflon® 2400 AF (Amorphic fluoroplastic) Tubing?
What number? In what units?
?

I thought I stated it. A link would help
Nevermind,
I found the English translation:
transport flux of a gas (rate of gas permeation per unit area), per unit transmembrane driving force, per unit membrane thickness

10-10 cm3 (STP)· cm /cm2 · s · cm-Hg
