A Styrofoam cup keeps drinks warm because the Styrofoam offers excellent insulation, which keeps the liquid warm inside. While a Styrofoam cup can keep drinks warm, a thermos container captures heat to keep drinks hotter for longer.
Styrofoam keeps things cold because it is made from polystyrene, a substance known for its low thermal conductivity, which is its ability to transfer heat. Styrofoam also uses millions of microscopic air bubbles as insulation to slow the progress of heat.
Styrofoam is a plastic made from petroleum, and it is also called a styrene monomer. Styrofoam is the brand name for polystyrene foam.
According to the Environmental Protection Agency, a Styrofoam cup will decompose in approximately 50 years and a Styrofoam buoy in about 80 years. It is a common myth that Styrofoam will not break down.
One method of cutting thin sheets of Styrofoam is to use a utility or razor knife. Users have a variety of other tools from which to choose, including a serrated knife, an electric knife, dental floss or an electric hot wire cutter. Cookie cutters also work to cut through thin pieces of foam for coo
Styrofoam, or foam #6, is usually recycled at large, central facilities following collection from decentralized drop-off sites. During recycling the foam is safely cleaned and sorted, ground into small particles, and melted into pellets that are used in other products. Many communities or municipali
Styrofoam works well as an insulator because it mostly consists of air confined to small pockets. These pockets hinder the convection process from carrying heat energy away from (or to) the substance inside the container.
Small-scale model houses can be made out of Styrofoam, using glue or pins and a utility knife. Alternatively, houses that are large enough to live in can be constructed out of Styrofoam using plastic ribbing and concrete for reinforcement.
Spray paint styrofoam by spraying the paint over a primer such as Mod Podge or Plaster of Paris. Applying a primer to the styrofoam prevents the chemicals in the spray paint from eating the foam.
Styrofoam does not decompose in the environment under normal circumstances. Much like plastic, Styrofoam is made from a polystyrene-based petroleum product that is not biodegradable. Plastic takes hundreds of years to decompose, and Styrofoam takes much longer because it is a stronger form of plasti
