Polystyrene is a plastic polymer, and along with many polymers may be made into a foam. But it has a high fire hazard because of the entrained air.
Indeed it is commonly used in that form in furniture, cars, packaging, refrigerators, and so on. A quite good thermal insulator.
The solid polystyrene is widely used for rigid consumer products, and is a fair electrical insulator
What else can I help you with?
Are plastic cups better than polystyrene cups?
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 polystyrene good for making an airplane?
Polystyrene can be used to make model aircraft (I'm assuming that's what you meant!) . Depron foam is better than white beaded foam because it is easier to sand and make smooth, also it is easier to repair if you crash the aircraft. If you can only get thin sheets of the stuff, simply glue them together.
Is cardboard cheaper than polystyrene?
In general, cardboard is usually cheaper than polystyrene due to the lower cost of raw materials and manufacturing processes involved in making cardboard. However, prices can vary based on factors like quality, quantity, and location.
Do thermocol balls float on water?
Yes, thermocol balls are made of expanded polystyrene foam, which is less dense than water. This is why thermocol balls will float on water.
How many cups are in 4 lbs of solid?
The answer depends on solid what! 4 lbs of osmium will occupy lot less space than 4 lbs of polystyrene foam, for example.
Is polystyrene ball heavier than iron ball?
No, iron is denser and heavier than polystyrene. An iron ball would weigh more than a polystyrene ball of the same size.
Is polystyrene less dence than water?
yes polystyrene is ls less dence than water because it floats
Where can you buy foam letters?
inexpensivesigns.com has them cheaper than most everywhere else. their 12 inch tall letters are only 1.99 a letter
Can polystyrene sink in water?
No, polystyrene is less dense than water, so it will float on the water's surface rather than sink.
What is the density of polystyrene foam?
Answer: The raw material of the Polystyrene has a density of around 1.05 g/l, or kg/m3 . which is a little bit more than water's Regarding the processed material there are two main types of polystyrene density-wise;EPS = Expanded PolyStyrene:most used in the range of: 10 - 50 g/lEXPS or XPS = EXtruded PolyStyrene:most used in the range of: 25 - 45 g/l
Is rubber heavier than polystyrene?
Yes.
