The process of making polystyrene is a simple yet complicated task and you need to be highly trained to carry it out. The process includes many up-down temperature changes (when the temperature goes from very hot to cold, back to very hot, to cold and so on).
The manufacture of polystyrene starts off as small styrene beads; the beads are exposed to steam. The steam causes the small beads of polystyrene to expand to up to 50 times their original volume. The next step in the process is conditioning. After the beads have expanded they go through a period of maturing, in order to reach an equal pressure and temperature. The beads are then placed into moulds and reheated with steam. The ready-made expanded beads expand further, filling the mould and fusing with one another. Together they now form customised products or blocks. When the process is over, near enough the whole volume of the expanded polystyrene is air (98%) and only 2% of it is polystyrene, which gives it its light weight.
Expanded polystyrene is made in the same way as original polystyrene but with a few different steps added in to the process. The original polystyrene melted mix is combined with a blowing agent, usually pentane at high pressure and temperature.
Each step of how polystyrene is made is done with precision; if a step is missed out or is done incorrectly the end product will be unavailable for use. The manufacture of polystyrene has to be done in large amounts so each one has to be made in a giant production factory.
A good thing about the manufacturing of polystyrene is that no harmful gases or chemicals are given off. The process for making polystyrene is very long winded due to the different heating and cooling processes each batch has to go through. Each time one batch is cooling the next batch is put in to heat, and vice versa.
The main process for making or manufacturing polystyrene is polymerization. This is when two styrene monomers (a single and a double bonded atom) bond or come together. A monomer is a single atom but when with more of the same atom it becomes a polymer. This is the main process for manufacturing polystyrene. The production is done between an estimated 300 degrees Celsius and 2000 degrees Celsius. These temperatures are so high as to allow the particles to form and bond.
Once the plastic has been adapted it can be used for many things. Popularly, it is used in packaging for fragile items and deliveries. It can also be used as installation for the home or as an art product.
