1. Polystyrene

   Polystyrene (PS) is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. Polystyrene can be solid or foamed. General-purpose polystyrene is clear, hard, and brittle. It is an inexpensive resin per unit weight. It is a poor barrier to oxygen and water vapour and has a relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several million tonnes per year. Polystyrene can be naturally transparent, but can be colored with colorants. Uses include protective packaging (such as packing peanuts and in the jewel cases used for storage of optical discs such as CDs and occasionally DVDs), containers, lids, bottles, trays, tumblers, disposable cutlery, in the making of models, and as an alternative material for phonograph records.As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled. This temperature behaviour is exploited for extrusion (as in Styrofoam) and also for molding and vacuum forming, since it can be cast into molds with fine detail. Under ASTM standards, polystyrene is regarded as not biodegradable. It is accumulating as a form of litter in the outside environment, particularly along shores and waterways, especially in its foam form, and in the Pacific Ocean.

1. polystyrene

   Polystyrene is a synthetic aromatic hydrocarbon polymer made from the monomer styrene, a liquid petrochemical. It is widely used in the manufacturing industry due to its light weight, strong plasticity, and insulation properties. Common applications include packaging materials, disposable cutlery, and insulation panels in construction. It can also exist in different forms such as solid or foam, the latter being popularly known as Styrofoam.

1. Polystyrene

   Polystyrene is a synthetic aromatic polymer made from the monomer styrene, a liquid petrochemical. Polystyrene can be rigid or foamed. General purpose polystyrene is clear, hard and brittle. It is a very inexpensive resin per unit weight. It is a rather poor barrier to oxygen and water vapor and has relatively low melting point. Polystyrene is one of the most widely used plastics, the scale of its production being several billion kilograms per year. Polystyrene can be naturally transparent, but can be colored with colorants. Uses include protective packaging, containers, lids, bottles, trays, tumblers, and disposable cutlery. As a thermoplastic polymer, polystyrene is in a solid state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled. This temperature behavior is exploited for extrusion, and also for molding and vacuum forming, since it can be cast into molds with fine detail. It is very slow to biodegrade and therefore a focus of controversy, since it is often abundant as a form of litter in the outdoor environment, particularly along shores and waterways especially in its foam form.

Examples of polystyrene in a Sentence

1. American Chemistry Council:

   Polystyrene foam packaging and containers provide business owners and consumers with a cost-effective and environmentally preferable choice that is ideal for protecting food and preventing food waste, particularly when used for food service. Foam packaging is generally more than 90 percent air and has a lighter environmental impact than alternatives.

2. Restaurant Action Alliance:

   The decision to ban foam food service products, which comprise only 10 percent of polystyrene foam material, will send the remaining 90 percent to landfills at the taxpayers' expense.

3. Fiorenzo Omenetto:

   A silk cup can be thrown away without harmful effects to the environment -- unlike a polystyrene cup, it's edible, so you can do smart packaging around food and can cook it with the food. It doesn't taste good, so I'm going to need some help with that.
