They are very flexible...good material...works well. I am very pleased with them. I don't know the material. Best wishes.

Yes and not under any conditions I can tell. Silicone in general tends to be nonreactive, outside of a chemistry lab or thrown in a fire, they should last many years. I have not damaged mine in any way, and I'm a clutz.

they are entirely silicone.....they are not overly tall though, that is the only thing I didn't care for, I use tall cups for my smoothies and are too short

I'm not 100% sure, but they feel more like silicone to me. It provides a very good seal if that helps.

I don't believe so. I'm pretty sure they're made of polypropylene only. There was no mention of BPA at the time of my purchase. I would definitely check with the seller to be 100% certain though. Good luck! :)

yep, 100% silicone. They are super flexible, not a bit stiff at all. Color is solid. I used them in my kids' lunches as food dividers but have yet to actually bake in them!

I don' t believe these are silicone, about 1/8.I bought these for my husband who has multiple foot problems, I don' believed they helped him. He is under the care, now, of a good doctor, who got him orthotics, fixed his toes, he is on medication for his feet too. Save your money and see a good foot doctor, he's done more for my.husband than any creams, pads and just about everything else we bought.

I think they are completely silicone (sides and back) and they are very cute!

Yes! They're made of plastic, but seem very sturdy. They're also easy to clean.

Yes. They are made of rubber, just like a rubber wristband on a sports watch.

They are a soft Silicone material, but they seem durable as well. So far they have worked wonderfully.

Yes, they are made of silicone and BPA free. They are really a great product. They clean up quickly and easily and they are very sturdy, even if you have kids that like to chew on things. I like them for my smoothies. :)

I believe they are 100% silicone. They are flexible and the color is solid. I love using these instead of my muffin pans. Cleaning these is so easy as you just run them under warm/hot water and then I just let them dry on a towel. I'm very happy that I purchased these! :)

I don't know. But I did read some reviews - not on Amazon - where people said it did contain silicone.

They are definitely not silicone. I am pretty sure they are polypropylene or LDPE. There is no identifying code on the bottom of the bottle, but there is a '5' on the inside of the cap. The look and feel is consistent with lab wash bottles made of those materials (I used to be a Chemist)

No. They are made of TPE (thermoplastic elastomer), which is a mixture of a plastic and a rubber polymer.
