I have recently been doing a bit of research into the chemical resistance of common materials that home distillers use in their equipment.
After thinking that silicone was completely safe, I read on
Cole Parmer's Site, and Silicone Chemical Resistance Chart @
http://www.cicoil.com/pdf/ChemC2.pdf ...all experiments point to Silicone being fine for ethanol & methanol, but completely unsafe in ANY manner for use with acetone (even at room temperature).
Considering foreshots consist of a high percentage of acetone (don't they?), I decided to conduct an experiment myself.
DISCLAIMER: I conducted this experiment for myself at home. It's not done in a science lab, and I'm not preaching to everybody that my results are conclusive for you...but they are for me :snooty: Make your own mind up.
EXPERIMENTI took material samples of:
1) Silicone Baking Sheet (Red one from Big W)
2) EPDM Tri-Clamp gasket
3) Silicone Tri-Clamp gasket
These samples were soaked in:
1) Mixed Early Heads/Late Tails
2) Methylated Spirits
3) Acetone
