Food and dairy containers, produce baskets, fast food containers, closures and vending cups and lids comprise the biggest commercial market of polystyrene. Polystyrene is also used in the durable goods industry in the manufacturing of domestic appliances, toys, household goods, electronic goods and furniture.
Because polystyrene is not susceptible to rough treatment it is favoured for use as packing materials. Polystyrene is used to protect goods that are shipped by stabilising the items inside the containers. Used for mail order due to its lightweight aspects, polystyrene doesn't add much to postage costs. The food industry uses polystyrene for climate control to keep produce fresh during transportation. Polystyrene is a common insulation product for walls, cavities, lofts and floors.
Hope I helped :-)
Polystyrene. the opaque white cups that you can make fingernails impressions in, are foamed polystyrene. Clear sups that you get on an airplane are general-purpose polystyrene.
Polystyrene in its foamed state is often used as an insulating material, or in packaging to protect goods in transit. In its rigid state, it can be used to manufacture many diverse goods.
summers swag ;)
The mass of polystyrene is easily estimated looking at its mass spectrum. The spectrum has the shape of a comb with a large number of teeth. Teeth are equally spaced. In the region between 1000 and 3000, the spacing is 104.12 g/mol. In the region between 3000 and 6000, the spacing is 104.18 g/mol. If the and the spacing is approximately 104.12 g/mol. The spacing changes
That depends on how you define "better" and what you're using it for.
The uses of rigid polystyrene are containers such as cosmetic bottles, TV cabinets. etc. In its sheet form it is used to make disposable cups.
producing disposable plastic cutlery
Polystyrene is NOT biodegradable

The atactic polystyrene is more crystalline than the syndiotactic polystyrene.
Because polystyrene is the polymer of the monomer styrene; poli in the Greek language has the meaning of many.
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.
Polystyrene is a kind of hard plastic.
Polystyrene is obtained by the polymerization of the monomer styrene.
Polystyrene is not very dense.
Polystyrene is today difficult to be recycled.
Polystyrene was discovered in Germany. Eduard Simon discovered it in 1839. He was from Berlin. Polystyrene is also called thermocole.
