Polystyrene ( PS ) is a tough, lightweight, petroleum based thermoplastic produced from the styrene monomer or a "polymer of styrene". Polymers are huge, twin molecules that are joined togethere. In the early stages of a polystyrene being created, it would be a basic thermoplastic, very similar to a solid white foam. To put it simply Polystyrene itself is a brand of plastic which can be easily extruded ( think Styrofoam ) and expanded ( EPS ). Though there are many unique types of polystyrene, the three most common would be Extruded polystyrene, Styrofoam ( Extruded Polystyrene ) and Expanded Polystyrene. However they contain great wear abilities and magnificent electrical insulation properties, which is one of the main reasons that make the material perfect for manufacturing processes. When it comes to food packaging polystyrene would probably be one of the most common material used by manufactures for the following reasons:
You may also find that DVD cases, parts of computers, model toys are made from polystyrene. Due to that it provided us with one of the worlds biggest contributors of material waste.
- Has more sanitation to public health.
- Inexpensive.
- Easy to shape.
