How to repair a hole in a refrigerator curved plastic ice tray? Answered

Our refrigerator ice tray has a 3 inch hole in the bottom. The hole is in the curved part of the floor of the tray. Is there a flexible plastic/acrylic I can use to repair the hole?

I would do a test with a cotton tip and some acetone to see if the plastic dissolves/goes soft.
MEK (primer fluid for pvc pipe welding) works too but should be hanfled with care.
In case the plastic does goe soft you can use a piece of ABS plastic that you cut to the desired size to fill the hole.
You can also dissolve some ABS in acetone to make a thick paste used as a filler/finnisher.
Takes a day or two to fully dry and harden - if you smell the solvent than it needs more time.

If the solvent trick does not work, cover the hole from one side with sticky tape and fill the hole with food grade epoxy resin.
Adding a fibreglass sheet can help in the hole is too big (more then 3cm in diameter).

I used a stuff called plastic epoxy many years ago to fix the plastic parts of an old refrigerator , the bottom drawers and the frame that it slid on. Structurally it worked great but it was an awful sick green color. It also smelled awful. Maybe they have a better type in white now especially since the insides of fridges are made mostly of plastic.

Big thing to keep in mind is that if it is in contact with ice that is used for drinking you need to use a glue that is food safe. Also consider if the repair can be cleaned easily. Poorly glued plastic can make areas that harbor bacteria.

Wikipedia says PMMA, what you call acrylic, can be solvent-welded, and heat-welded.

https://en.wikipedia.org/wiki/Poly%28methyl_methac...

One of the solvents they suggest is cyanoacrylate, superglue, so if you have all the pieces that broke out of the hole, then maybe you could put them all back together, gluing them with superglue.

If you don't have the pieces that came out of the hole, I guess you have to come up with a patch to fit over, or under, the hole, and that might be tricky if you want the patch to also be made of acrylic, and it has to fit to a curved surface.

If the patch itself is allowed to be a material other than acrylic, then this opens up all kinds of possibilities.

For example, you could maybe patch the hole using duct tape, or some other kind of tape, preferably a kind that continues to stay sticky at freezing temperatures.
