because it can protect the DVD cos it is hard and brittle. Hope this helps
Ordinary polystyrene is better known as cristal polystyrene or GPPS (General purpose polystyrene) It is a hard very transparant and britlle plastic. One of the best know uses is cd-box. To improve the toughness of this plastic rubber is added during the manufacture. This synthetic rubber (polybutadiene) is divided trough the polystyrene in the form of small droplets ,The size and the composition of the rubber droplets will determine final properties. A lot of applications will be made with mixtures of GPPS and HIPS (HIPS is high impact polystyrene). The stiffness of HIPS is a lot lower than the stiffness of GPPS, hence the mixtures. One well known application is yoghurt cups.
Conductive polystyrene is a type of polystyrene that has been modified to conduct electricity. It has properties such as high thermal stability, chemical resistance, and good mechanical strength. Conductive polystyrene is commonly used in applications such as electronic components, packaging materials, and static control products.
Disposable cutlery, plastic models, CD and DVD cases, and smoke detector housings. Products made from foamed polystyrene are nearly ubiquitous, for example packing materials, insulation, and foam drink cups.
Somewhat oversimplifying it a DVD (or CD) is a sandwich of two outer layers of polycarbonate plastic with a microscopically thin layer of aluminum, tantalum, or a optically reflective low melting point plastic between the outer layers. Standard factory made read only disks use aluminum in this inner layer for durability, the writable disks use either tantalum or a plastic in this inner layer to permit writing with the LASER as well as reading (which is used depends on the method of writing used).
In polystyrene, the composites commonly used are typically mineral fillers like talc and calcium carbonate. These composites help improve the mechanical properties and performance of the polystyrene, making it stronger and more heat-resistant.
High impact polystyrene is used in windmills for its lightweight and durable properties. It is an ideal material for creating components such as blades and nacelles that require strength and impact resistance to withstand harsh weather conditions. Additionally, high impact polystyrene is cost-effective and can be easily molded into complex shapes, making it a popular choice for wind turbine construction.
i recently found this out and hips stands for high impact polystyrene but iam not actually sure what its used for
HIPS High Impact Polystyrene is particularly suitable for thermoforming, it is a tough, rigid material and its high impact strength means it can be guillotined, punched, routered or sawn without difficulty.

HIPS, which stands for High Impact Polystyrene, is an insulator. Polystyrene is a type of plastic that does not conduct electricity well due to its molecular structure, which lacks free-moving electrons necessary for conduction. Therefore, HIPS is commonly used in applications where electrical insulation is required.
They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.

Not AS the wall of a house but it can be used as part of the wall of a house (as insulation).

Polystyrene can be used in various industries like Polystyrene Packaging, Construction, Display, Exhibition, Signs, and all areas of the foam industry. Various different items can be produced from polystyrene. For a complete range and details about products please visit: http://www.polystyrene.uk.com/
Expanded polystyrene (EPS) is a lightweight, rigid foam material made by expanding polystyrene beads. It is commonly used for insulation, packaging, and construction due to its excellent thermal insulation properties and shock-absorbing capabilities. Polystyrene, on the other hand, is a solid plastic material that is more rigid and dense than EPS. It is often used in food packaging, disposable cups, and other products requiring a solid plastic material. The differences in density and structure between EPS and polystyrene impact their uses and applications. EPS is preferred for applications requiring lightweight insulation and cushioning, while polystyrene is better suited for products that need a more solid and rigid material.
