Foam - styrofoam is an excellent insulator. With a hot drink - you want it to remain hot - so you do NOT want heat to move out of the drink to the cooler outside. The styrofoam vastly reduces this heat flow.
With a cold drink, the reverse is true. You want it to remain cold so you do not want heat to move from your hand or the outside atmosphere into the drink. The styrofoam vastly reduces this heat flow.
Yes! It decomposes.
areated plastic"Foam" Is Actually Expanded Poloystyrene (EPS - Foam Coolers, Foam Cups, Etc.)When you buy foam cups or foam fishing buckets or even foam coolers like the ones we make at LoBoy, you're buying a product made of Expanded Polystyrene (or, "EPS" for short). EPS foam is an awesome, space-age material that is environmentally friendly because it is recyclable as long as it's not ruined by screen printing or other processes that eat into the foam with nasty industrial chemicals. Some EPS foam manufacturers mess up its recyclability by painting over the pure material rather than ensuring that it is reusable.Many products these days are made from EPS foam - floating boat docks, highway construction, homes (insulated walls), foam coolers, foam shipping containers that keep seafood and pharmaceuticals from spoiling (a shipping process known as "Cold Chain Shipping"), foam cups and plates, EPS foam packaging protection for many of the things we buy in stores.The thing about good EPS foam products is, again, that they can be recycled for reuse. LoBoy maintains a 100% EPS foam recycling program, and we hope to see most people begin setting aside the foam products they would normally throw away so that what usually goes in the trash instead becomes a form of treasure that leads to more jobs.
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.
Because the plastic reflects bubbles more than paper or ceramic.
i make the phenolic foam out of both of them in the same formula it works out fairly well but i am engineering it to get top performance out of the polymers.
To keep it cold, as the body temperature of the hand can warm the drink.
Foam lets extra cold air reach the water
Heat cannot travel through the foam material so the drink stays well insulated inside the foam cup.
Root beer
a foam cup i guess but what kind of question is that
paper or foam cups
Yes! It decomposes.
Yes You Can
paper or foam cups
paper or foam cups
Yes, they are.
just about 35! wow isn't that a big number
