what is the hot water bottle made of?

According to the product description when I got mine, it's made of a "thermoplastic material," so it's a synthetic substance which becomes moldable when heated, and retains its shape when cooled.

Cap is made of plastic. I don't know how heat resistant it is but I wouldn't try boiling water with the cap on.

My guess, it's a rubberized silicon blend of some sort. It stays cool, grips well and makes hanging on to a hot pot easy. The more I use this pot the better I like it. Use it every day. Heat water for tea and coffee.

It's made of Plastic. Stainlless steel warm up the water. It is perfect like it is.

No, this bottle is not meant for hot liquids, as with every stainless steel water bottle that is not a thermal one, the container becomes hot when filled with hot liquids.

Lid and top are made out of some sort of metal, probably stainless steel. The spout is made out of a hard plastic and the inside of the spout cap is also made out of the same hard plastic. I have found that a downside of this particular plastic threaded spout and cap is that it gets a little funky easier than other bottles.

It appears to be stainless steel on the inside--not glass or plastic or anything else. It functions well--holds a lot of water, keeps it cold, or cool, for a long time, pours well, and looks sharp. Several people have commented on how sharp it looks.

Probably about 2 cups of water. Stays warm all night. Excellent hot water bottles.

Not entirely sure but the Zojirushi website has lots of info. It's a hard plastic with what I think is gray silicone gasket. The lid disassembles for cleaning into 3 pieces. I can't say enough about this mug. If maintaining temperature over SEVERAL hours (although I've only used it for hot) is important to you, this thing is the bomb. And it's beautifully designed.

The looped cap that comes standard with the Hydro Flask is made of all plastic with a silicone o-ring gasket/seal. They also sell a flat-top cap that is made of both plastic (the top part), and stainless steel (the bottom part that screws into the bottle), this also has the silicone o-ring seal/gasket.

It appears to be a simple plastic/PVC type bottle. I wondered the same thing given the highly solvent nature of DMSO.

yes. same material as outer shell. it was described as styro-foam lined between the two plastics. When inst-hot water eas used to make beverage, temp held-up for about half hour, very slowly cooling, and by time stated the beverage had been completely consumed. snap-on top is not thermal rated, just plastic with a neat sliding opening cover. Great for short term, 20 oz of bev. if need to keep hot longer, make a shorter pour from a good thermos . like a Stanley or Hot Pot.

The bottle is made of hard plastic and has an indent where you hold it. It also has a ring at the top which makes it easy to carry. Easy to wash and no problem with leaking.

It is plastic. Yes the water touches it, but it is made in such a fashion that there is no need to worry about it getting hot. It is like a duel pane window so you can touch the outside ( which is good since that is where the handle is) and it is barely warm with boiling water inside.

The main container made of glass. So, it also makes great hot coffee! Hope you enjoy it as much as I do if you get it!

Metal. Works really well, I like it. l do as they suggest and put hot water in it for a few minutes, pour it out, the put in the stuff i want to keep hot. Having the insides hot already keeps the stuff hot longer. The outside also heats up fast if you run hot water over it.

Stainless Steel, and I might add that it is VERY good at keeping hot drinks hot for a long time.
