The majority of plastic cups can be reused or recycled. Polystyrene, or foam, cups are not widely recyclable. Cost wise, plastic cups tend to more inexpensive than polystyrene cups.

Is styrofoam the same as polystyrene?
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.
Is styrofoam polar or nonpolar?
Thermoplastic is a term that refers to a substance turning into plastic when exposed to extreme temperatures. This would make Styrofoam thermoplastic.
Why disposable cups are better then plastic cups?
Disposable paper cups can be microwaved and stored with many more types of liquids than a plastic cup. More information can be found through Anbao Cup manufacturer in China.
What is HIPS plastic?
HIPS High Impact Polystyrene is particularly suitable for thermoforming, it is a tough, rigid material and its high impact strength means it can be guillotined, punched, routered or sawn without difficulty.
Why are paper cups better than plastic cups?
I think it depends very much on what you mean by "better". If you mean "better" from an environmental perspective, I don't necessarily think they are. The popular view is that paper cups biodegrade, and are therefore "green", whilst plastic cups do not biodegrade and therefore litter the environment. However, plastic cups only litter the environment because people are lazy and don't dispose of them appropriately. They COULD be recycled (depending on which plastic was being used to fabricate them) if anyone was interested in doing so. Also, it is not true that paper cups (or paper anything else) readily degrades in landfill sites (which is where more waste ends up when it isn't recycled). Landfill sites are not useful for aerobic biodegredation, and paper items placed in them stay intact for literally years.
Does a polystyrene cup hold more heat than a plastic cup?
Polystyrene
Are plastic cups better for string telephones than metal cups?
I would say that plastic cups are better for string telephones because you cant get string through a metal cup.

What are the differences between high impact polystyrene and ordinary polystyrene?
Ordinary polystyrene is better known as cristal polystyrene or GPPS (General purpose polystyrene) It is a hard very transparant and britlle plastic. One of the best know uses is cd-box. To improve the toughness of this plastic rubber is added during the manufacture. This synthetic rubber (polybutadiene) is divided trough the polystyrene in the form of small droplets ,The size and the composition of the rubber droplets will determine final properties. A lot of applications will be made with mixtures of GPPS and HIPS (HIPS is high impact polystyrene). The stiffness of HIPS is a lot lower than the stiffness of GPPS, hence the mixtures. One well known application is yoghurt cups.

Is polypropylene better than polystyrene?
That depends on how you define "better" and what you're using it for.
Which is a better conductor wood or polystyrene?
Polystyrene is a better insulator. It is often used as insulation on houses.
Examples of objects whose density is less than water's?
polystyrene / styrofoam plastic wood / cork / ice
Is Polystyrene a good thermal conductor?
No, it's not, though it's better than you might think if you equate polystyrene with Styrofoam. Styrofoam is made of polystyrene, but it's the trapped air that makes it such a good insulator.
What is HIPS plastic?
HIPS High Impact Polystyrene is particularly suitable for thermoforming, it is a tough, rigid material and its high impact strength means it can be guillotined, punched, routered or sawn without difficulty.
What type of cup will keep water the coldest a styrofoam cup or plastic cup?
Styrofoam insulates better than a single layer of plastic. If, however, you have one of those plastic cups that have an outer and an inner "wall" with a sealed air space in between, that should work better than the Styrofoam.
