Thermosetting
No, high Impact Polystyrene (HIPS) is a thermoplastic. It melts when heated.
It is a thermoplastic! :)
a synthetic thermoplastic material obtained by polymerizing styrene; used as a white rigid foam (expanded polystyrene) for insulating and packing and as a glasslike material in light fittings and water tanks
polystyrene, alkyd and hydrocarbonthank you xxx
The uses of rigid polystyrene are containers such as cosmetic bottles, TV cabinets. etc. In its sheet form it is used to make disposable cups.
Polystyrene is a very poor conductor of heat. This is why its used as an insulator in some products.

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.
Polystyrene is a synthetic polymer made from the monomer styrene. This monomer is a liquid petrochemical and can be rigid or foam.
