Is there any type of glue made for styrofoam? Answered

I'm working on a school project where I have to layer pieces of styrofoam but all the glues I have tried (hot glue, spray adhesive glue) have corroded the styrofoam way to much. Is there a special glue that will not eat away at it? Thanks!

Yes, UHU POR, made for styrofoam. This a contact adhesive, and is supplied in tubes (40g), tins (220gr & 570gr) & cans (370gr). UHU also have a technical datasheet.

The "POR" appears to match a Badische Anilin & Soda-Fabrik (BASF, DE) trademark, "Styropor". "Styrofoam" is a Dow Chemical Company (DCC US) trademark. Each are for expanded polystyrene (EPS) products. Both BASF & DCC have a long history with polystyrene. Polysyrene was discovered in 1839, BASF founded in 1861, and they invented Styropor in 1951. DCC introduced Styrofoam products to the US in 1954 (derived from ThoughtCo. website).

1932: "As was customary to name stationery goods, he [August Fischer] named his glue after a bird, the [eagle] owl, familiar to the Black Forest: UHU The All Purpose Adhesive. Though it has become a worldwide brand, UHU remains deeply rooted in Bühl." (derived from UHU website).

Use yellow carpenter's glue, not white glue. PVA (yellow glue) is water resistant when cured and will make a bond in styrofoam that is stronger than the  foam itself.
To do the glue up, remove the glaze from the foam with a piece of fine grit sandpaper, apply a light coat of glue to both pieces, use masking tape to hold the pieces together and let cure overnight.

I went to Michael's on the same search and found (drum roll please) Make It FUN brand StyroGlue...  Which looks and acts to me just exactly like white glue.  I wanted styrofoam glue that is also waterproof and have yet to find it.  This is water based, so not water proof, and my cooler from reclaimed styro blocks is a mess.  Let me know if you have better luck, my friend!

Liquid-nails makes a paneling glue that i have used on styrofoam successfully. just buy the BIG tube in a caulking gun sized costs not much more than the little tubes of glues.  I would also give REGULAR liquid nails a try.  seems to me regular liquid nails glue might also work.

My best answer is exactly what NobodyInParticular said, just use white glue. However, I wanted to warn you that if you are experimenting with different glue types, do not use superglue/krazy glue/cyanoacrylate. It reacts with styrofoam ti create a nasty little cloud of cyanide vapor. I accidentally spilled a drop on some foam a while back, the tiny little puff of smoke drifted into my face. I was instantly blinded and could see nothing for about five minutes, and had irritated eyes for a few hours. Not trying to be a doomsayer, just trying to make a point and a warning.

What's wrong with plain old white glue? It's cheap, strong, and nontoxic.
