Haven't tried it, but the manufacturer claims it's microwave safe. I believe most food-grade silicone products are microwave safe.

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

The lid and the mounting surface for the lid are not silicone. The rest of it is food grade silicone though.

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

I just bought these Gummy Bear Trays 2 weeks ago. The material feels rubbery and very sturdy, used it to make jello. I *ASSUME* it might be silicone. Don't know about the chemical composition.

Although I am not an expert... I believe that most silicone is safe up to 500 degees. I have used them in a skillet at medium high heat without any damage to them. Hope this helps.

Nope. Silicone must be removed. Curses to anyone who used silicone as it is a PITA :(

I don't know what grade these are. I just bought them on Amazon and don't still have the package. I would ask the manufacturer.

Silicone does not contain BPA, PVC or Pthalates. Silicone is a synthetic rubber that is elementally different. It is the hard plastic handle part does not say for sure that it is BPA free. It does say it is dishwasher safe which means it can withstand high temp. http://www.hhs.gov/safety/bpa/

I think it's silicone rubber. Why not call the Sizzix company. I'm sure they'll tell you.

It is a silicone for me. Soft and plyable even at -5F (tested). I own 2 of them, and love both!

I believe it is. Translucent somewhat soft silicone. I popped it in and immediately saw 100% improvement.

I did a live chat this morning with support at Nordic Track and they gave me the part #219170 which is very close to the number you have. Support service says it's not silicone and they don't recommend silicone, but from other reviews it seems there is lots of confusion about this. Another place I read it is water based silicone. Don't know if that makes any difference. I am going to order the ICON product because it's what Nordic Track recommends. However their site would cost considerably more... $43.37

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!
