Well there is:
Kitchen wear
Disposable cup
Toys
The best insulator of heat is probably polystyrene foam or fiber glass.
Wool and cotton.
polystyrene is not heavy can be heavy in certain places though
Polystyrene
"Conventional" just means 'the most usually used". When referring to materials this means that the things which are "conventional" will vary according to what the task of the material is. Slate is a conventional material for roofing houses, but not for clothing Wool is a conventional material for clothing, but not for making bicycles Steel is a conventional material for making bicycles, but not for heating homes Coal is a conventional material for heating homes, but not for growing plants in and so on.
Polystyrene is not a hazardous material (dangerous good) in transportation. However, in circumstances where a fire might be a problem, polystyrene, which can readily and rapidly burn, can be a very hazardous material.
Acrylic and Polystyrene both are THERMOPLASTICS.
hydrocarbons
polystyrene
extruded polystyrene
liquid !!
Silicone is best for that.

The law of polystyrene affects consumers because of the chemmicals inside the material and the polystyrene is burned underground and the chmicals gets into the environment which can make consumers sick
Like many other plastics, polystyrene is a polymer derivative of oil. It can be, but often is not, recycled. This is because of a lack of plants capable of processing the material, and its low yield when processed from its expanded foam form. In the cases where it is recycled, it is often used in other plastics and materials. Furthermore, plastics generally decompose very slowly, and polystyrene is no exception. This means the material stays in the ground without breaking for a long time when placed in a landfill Historically, the material has been expanded using Chlorofluorocarbons (CFC's), increasing awareness and regulation have led to the use of other, more environmentally sound substances. In addition, some cities have imposed bans on the material for packaging. Polystyrene is a common and useful material, however, its long decomposition time and infrequent reprocessing, as well as its disruptive introduction into ecosystems contribute to its reputation for not being environmentally friendly. src: http://en.wikipedia.org/wiki/Polystyrene
Polystyrene is a very poor conductor of heat. This is why its used as an insulator in some products.
polystyrene foam cups and composite Wood material like snake glass fiber etc
