Can these hole propylene glycol without dissolving?

No, they are very pliable & would dissolve. Even when water touches them they begin to do that. I hope you are not trying to do something harmful to something unable to protect itself. If so, try it on yourself first.

Definitely not for propylene glycol. Cannot imagine what you are trying to do, in fact your request sounds scary.

No unfortunately you can't. You would need a patch kit to do that. Patch kits are really cheap and pretty easy to use. The liquid in the slime does a little to help patch a hole but the pieces of fragments in the slime do most of the hole clogging. slime is ment to be put into the tube and it works as the air rushes out and the little fragments stop up the hole as they are too large to exit through the hole.

Only if you fill them with a dry ingredient. No liquids or they WILL dissolve.

I'm looking at the ingredients list on my bottle and from what I can see, it does not contain any propylene glycol. Hope that helps!

These are not chemical packs so they have to be frozen before use (chemical freeze packs are single use anyway). And the other reviewer is right - they are cheaply made and will leak eventually. Unfortunately, they are the only ones I've found that fit my insulin pouch, so I try to be careful and make them last as long as possible.

Yes! Just be careful not to puncture and take care in sealing. Yes, they would not be so useful without being reuseable.

I am no expert, but I have a BA in chemistry and an MS in an engineering discipline FWIW. Seems by looking up the eutectic that you'd need a 50/50 mix of pure propylene glycol and water, from the Engineering Toolbox (http://www.engineeringtoolbox.com/propylene-glycol-d_363.html). Doubt this stuff will damage your system over time, but I can't say if something odd would happen over years such as bacterial growth etc.

I can't imagine why they wouldn't. However, you can't soak them or they dissolve into dust so that could be a problem

No, I just put it into slightly warm water and it dissolves easily. But it doesn't effervese.

I'd be afraid the squares would burst once they started to melt. Seal the sheet inside a big zip-lock bag, and if they did pop, at least it wouldn't make a mess. These do seem to hold the fluid better than the Cryopaks I was buying, but sitting on them? I don't know.

Sure, the two ingredients are only activated when mixed together, so the epoxy won't harden in the tube between uses.

These are gelatin caps. Gelatin will dissolve when it comes in contact with anything wet. I would think that they would not be suitable for gel only dry ingredients.

I don't think so, I would think you would need the heat to dissolve the freeze dried pieces. However, I have never tried so I don't know for sure. Perhaps it would take a much longer time, but could work?

If I happen not to use an entire package, I usually stick them in the freezer and have used them months later. They don't actually freeze solid because of the brine solution. I did not notice any freezer burn or change in texture.

Never tried to dissolve them in water. I don't think they would. If they did, it would take too long.

Yes they dissolve in water---I use it to make a normal saline solution. But they don't dissolve immediately so be sure to give plenty of time. Maybe prepare the night before. They are very hard and dense , about the size of a dime.

Yes. We use water and within a minute or two and a little swirling, it dissolves easily.
