What is polystyrene used for?
- Polystyrene (PS) plastic is a thermoplastic that is naturally transparent and available both as a standard solid plastic and in the form of a rigid foam material. PS plastic is widely used in a number of consumer product applications, and is also particularly useful for commercial packaging. Where does polystyrene come from?
What is the shape of polystyrene?
- Polystyrene. Solid polystyrene is transparent, owing to these large, ring-shaped molecular groups, which prevent the polymer chains from packing into close, crystalline arrangements. In addition, the phenyl rings restrict rotation of the chains around the carbon -carbon bonds, lending the polymer its noted rigidity.
Is polystyrene biodegradable?
- Polystyrene is compound is non-biodegradable with a couple of exceptions. It is easily dissolved by many aromatic hydrocarbon solvents and chlorinated solvents. It is widely used in the food-service industry as rigid trays, containers, disposable eating plates, bowls, etc.
What is high impact polystyrene?
- Polystyrene. In order to reduce brittleness and improve impact strength, more than half of all polystyrene produced is blended with 5 to 10 percent butadiene rubber. This blend, suitable for toys and appliance parts, is marketed as high-impact polystyrene (HIPS).
