Best Glue for Styrofoam repairs. I broke my incubator.

When cleaning my Hovabator I broke a small part of the Styrofoam and I was wondering what the absolute best glue to use... I know that Super Glue dissolves styrofoam so definitely not that.

Good ol Gorilla Glue works great, low temp hot glue , loctite.

Good ol' caulking-silicone. Any glue without solvent.

that's where I have been leaning because what ever I use it needs to be waterproof as well as not going to dissolve the Styrofoam. Right now I am trying to find a scrap example of the same quality Styrofoam and do a few tests before I try anything.

Important: Silicone, not Acrylic! The Acrylic stuff dissolves Styrofoam slowly. And best is the Silicone that smells like Ammonia, not the stuff that smells like vinegar. The vinegar stuff does not dissolve the styrofoam, but it doesn't stick as well as the other stuff. I used plain old gray silicone caulking to glue styrofoam boards to the iron sheets that make the ceiling of my cold pantry and it sticks like welded.

Silicone is just an overall better caulk, I never buy Acrylic even for general purpose caulking

Can you post a picture of the broken parts?

Just a small piece that I was holding as I tried to submerge it to wash it. It could still run with that piece missing but repairing it would help keep temps and Humidity more stable,

The issue with Carpenters glue or wood glues in general is that they dissolve in water and when I incubate I am washing the incubator every 3 weeks. Although I can always reglue it after I wash it.
