According to HotRdd :
You need to test a few spots to see what will hold. I love to use crazy glue
(Cyanoacrylate Adhesives) but it only works on certain plastics and
basically solvent welds them together. In some cases it's stronger than the
original bond.

CA doesn't solvent weld most plastics any more than it does on metal
or wood. It also isn't that good under continuous weight bearing duty
The only thing CA (superglue) works on is human skin. It is worthless
for everything else as it is too damn brittle.

Try acetone. It temporarilly disolves the plastic into a goo. Brush some
on the edge of both pieces. Touch to gooey sides together, and when it "dries"
it'll be a single piece of plastic.

Depends on the plastic. Model airplane glue is little more than
polystyrene dissolved in acetone to give it some body. If your
shelving is polystyrene (good chance), either acetone or model airplane
glue will work more or less the same, and model airplane glue is
easier to work with - won't dribble all over the place. Just
get fresh stuff - semi-congealed stuff won't work...

However, not all plastics are polystyrene. Acetone won't do a thing
to polyethylene for example. Essentially nothing will. Some plastics
just don't "glue". The "slippery ones" generally don't, no matter what
you use.
