You'll want to stick with the same parent material. There should be an identifying code on the back of the part. If you are for certain it's abs, then use abs plastic welding rod.
If the damage is just a crack, you can also go the hot staple route. For most bumper repairs that I do, I usually go this route. It gives the repair some kind of mechanical structure, and then I usually use a mesh screen combined with 3M's semi rigid epoxy(4240), and then I "V" out the front side, and do a cosmetic repair on the front side either either using 3M's flexible plastic repair (5887) or more of the same semi rigid repair. Keep in mind that you'll need to use an adhesion promotor between each coat of repair material, spraying very light coats, and letting it dry completely. I'd also suggest staying away from any sandpaper on the front side of the repair rougher than 150. Anything less than that and you'll have little "fuzzies" that'll show up when you prime the piece.
