I could be wrong, but No resin is needed to make Polystyrene hard.
Polystyrene is a thermoplastic substance, which is in solid (glassy) state at room temperature, but flows if heated above its glass transition temperature (for molding or extrusion), and becoming solid again when cooling off.

What is the difference between rigid polystyrene plastic and expanded polystyrene?
Rigid polystyrene plastic is a closed cell of light weight, rigid & foam plastic that is derived from petroleum and natural gas by products. It is hard plastic in one word. This is used to make plastic containers and insulators. On the other hand, expanded polystyrene is derived by expanding the regular foam molecules by 50 times their volume using a blowing agent (pentane gas). This is used to make packaging materials.

Can i use high impact polystyrene for lost foam casting?
No. High impact polystyrene is a very hard plastic. If you tried doing a lost-foam casting you'd just make a mess.You make a lost-foam casting by creating a styrofoam model of your finished piece, packing casting sand around it to create a mold, then pouring metal into the mold. When the hot metal touches the foam, it vaporizes.You could make your model out of high impact polystyrene then use that to create a cope and drag mold.
