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.

Polystyrene is available in several grades, primarily categorized as general-purpose polystyrene (GPPS), high-impact polystyrene (HIPS), and expandable polystyrene (EPS). GPPS is clear and rigid, making it suitable for applications like packaging and disposable cutlery. HIPS contains rubber additives for increased toughness and impact resistance, often used in consumer products and automotive parts. EPS is lightweight and insulative, commonly used in packaging and insulation materials.

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.
High impact polystyrene (HIPS) is used in mini windmills primarily due to its excellent strength-to-weight ratio, which allows for lightweight yet durable blades. Its ease of molding and shaping enables the creation of complex designs that can optimize aerodynamic efficiency. Additionally, HIPS is resistant to weathering and UV radiation, making it suitable for outdoor applications. Overall, these properties contribute to the performance and longevity of mini windmills.
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.

Conductive polystyrene is commonly used in applications such as electronic components, packaging materials, and static control products.
Not AS the wall of a house but it can be used as part of the wall of a house (as insulation).
