Polystyrene is a very poor conductor of heat. This is why its used as an insulator in some products.
Polyethylene is a thermoplastic polymer.
Polyvinyl chloride is a thermoplastic polymer.
Polythene, also known as polyethylene, is a thermoplastic, not a thermosetting plastic. Thermoplastics can be reheated and reshaped multiple times without affecting their properties, while thermosetting plastics undergo a chemical change during heating and cannot be reshaped once set.
Vacuum forming is one of the most common methods of processing plastic. The vacuum forming process involves heating a sheet of plastic until it is soft.

thermoforming plastic is completley the oppisite of thermosetting!

No, HIPS (High-Impact Polystyrene) is a thermoplastic, not a thermosetting plastic. Thermoplastics can be melted and reshaped multiple times, while thermosetting plastics undergo a chemical reaction during curing that makes them rigid and non-meltable.
It is a thermoplastic! :)

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.

They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.
