Facts about Polystyrene

Have you ever wondered what those small beads in your bean bags actually are? Well, those beads are polystyrene or Styrofoam. This kind of material is formed by styrene molecules. The double bond found between the CH2 and CH portions of the molecule can be rearranged in order to form a bond with any nearby styrene molecules and produce polystyrene. It can be used to create a sturdy, impact-resistant plastic found in some types of furniture, utensils, glasses, and cabinets for computer monitors. When heat is applied to polystyrene and air is blown through the substance, it can form Styrofoam, which is a lightweight insulator.

Polystyrene is classified as a thermoplastic substance. This means that it has a solid or glassy state at room temperature, but it can flow once it gets heated above its glass transition temperature. However, it can become solid again once it cools off. Pure polystyrene in its solid state is a hard and colourless plastic that has a limited amount of flexibility. It can then be cast in various moulds and take on different shapes and details. Furthermore, the material can either be transparent or coloured.

Solid types of polystyrene can be used in making disposable utensils, cases for CDs and DVDs, plastic models, and housings for smoke detectors. Some of the most common products made from the material are packing materials and foam drinking cups.

So, the next time that you are lounging on your bean bag furniture, think about the wonders of polystyrene and how it has made modern living more comfortable and convenient.
