Styrofoam is a common material used for packaging and insulation. Do you ever wonder how it’s made? Polystyrene processing is the key.
The production of styrofoam starts with polystyrene, a synthetic polymer. It is fed into a machine, where it is melted at high temperatures. Once it has turned into a liquid, it is injected into molds. The molds determine the shape and size of the styrofoam.
As soon as the styrofoam has taken its shape, it’s left to cool. The cooling process solidifies the liquid polystyrene into the now-familiar white foam. After the styrofoam cools, it’s ready to be used.
But wait, there’s more. Sometimes, production requires additional steps. For example, manufacturers can add chemicals to give the styrofoam different properties. Some chemicals can make it more durable, while others can make it more resistant to heat.
Polystyrene processing is a complex procedure that requires skilled professionals. When you open a package or see a styrofoam cup, remember that it went through a multistep course of manufacturing.
