Polystyrene, commonly called foam or Styrofoam, is a popular material used for packaging food and electronics. Did you ever wonder how it’s made? Let’s take a closer look at polystyrene processing.
The process starts with styrene, a liquid hydrocarbon obtained from petroleum. It’s mixed with a catalyst and heated to create a thick, gooey liquid called polystyrene. This liquid can be molded into any shape or size, making it versatile for various products.
Once molded, polystyrene goes through a process called expansion. This involves adding steam and pressure, causing the polystyrene to puff up and become the foam that we’re familiar with. This expanded foam has a low density, making it lightweight and easy to transport.
However, polystyrene processing can have negative environmental impacts. When disposed of improperly, foam can take hundreds of years to decompose and pose a danger to wildlife. That’s why many cities have banned the use of foam food containers and encourage recycling programs.
Polystyrene processing is an intricate method that involves the use of petroleum and a heating process. Though it provides us with convenient and cost-effective packaging options, it can also have a detrimental effect on our environment. It’s important to dispose of foam properly, recycle it when possible, and even consider using alternative materials for packaging.
