CH4 / Plastic Interaction

05/13/2007 1:16 PM

Hello! I am looking for plastic material that disintegrates (i.e. loses its mechanical strength) when it is exposed to methane (CH4) gas. Can anybody help me?

Hmmm . . . I'm not a chemist, but I thought I'd put in my two cents worth anyway -- hope you like a little levity on Monday mornings . . . Mix the methane with O2 and raise the temperature to the flash point, then the plastic will disintegrate!

Adding to the levity chain, since our poster is from Saskatchewan, this might well be a farm-related application, in which case the methane "fuse" should be made of nostril hairs, as mine surely curl with a good whiff of manure!

Why do you want it to lose strength when exposed to methane. Methane is not particularly very reactive with other organic compounds, so this might be hard. However, since it is not polar, many organic polymers that are hydrophobic, are permeable to methane. So I guess the question is what is the intended use and performance parameters?

Thank you for your interest. I am trying to make a mechanical "fuse" that will be activated when it is exposed to methane gas.
