Silicone coated parchment paper: Unsafe compatibility with n-butane

[KonradZuse]

Hahaha parchment doesnt come off in the oil nor does it change the flavor or smell. Wax from wax paper yes. Why on earth would you scrape parchment paper?

Like I said there was oil all over the paper so I tried to get it off, and parchment came off .

I meant why wouldnt you fold, stick n yank?

just found this ... does not sound that bad at all....



Silicone rubber also has excellent resistance to
solvents and other chemicals. It is essentially
unaffected by polar organic compounds (aniline,
alcohol, etc.) or dilute acids or bases, with the
increase in volume due to swelling in the range of only
10%–15%. Silicone rubber does swell in non-polar
organic compounds like benzene, toluene and
gasoline; but unlike most organic rubbers, it does not
decompose or dissolve, and will return to its former
state when the solvent is removed. Silicone rubber is,
however, adversely affected by strong acids and
bases, so it should not be used where it will come in
contact with such chemicals.

So for our uses definately good to go or not ?

not talking parchment... mean more mats n stuff, but for storage in parchment u can still say : if it does not stick to the paper, big part of the silicone should be where it is supposed to be...

blasting in it other story...

Good question! As they don't directly address it, I sent their technical support staff an inquiry, asking for links or data showing test results using aliphatic alkanes like n and Isobutane.

More once I receive a response!

Any new data re this? Because of the lingering doubt, I'm catching the solution in Teflon membrane lining my Petri dishes.
