Polystyrene (PS) / ˌpɒliˈstaɪriːn / is a synthetic polymer made from monomers of the aromatic hydrocarbon styrene. [5] . 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 air and water vapor and has a relatively low melting point. [6] .

Polystyrene, a hard, stiff, brilliantly transparent synthetic resin produced by the polymerization of styrene. It is widely employed in the food-service industry as rigid trays and containers, disposable eating utensils, and foamed cups, plates, and bowls.

May 21, 2022 · Polystyrene, also known as poly-phenylethene, is a polymer made up of repeating molecules called styrene. It is a thermoplastic polymer, meaning it softens and melts when heated and can be reused. It is an excellent electrical insulator and is resistant to chemicals such as acids and bases.

Polystyrene is an optically clear, cheap, easily molded polymer, familiar as the standard “jewel” CD case. In its simplest form, PS is brittle. Its mechanical properties are dramatically improved by blending with polybutadiene, but with a loss of optical transparency.

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.

Polystyrene is a hard, brilliantly transparent, stiff resin. It is produced by the polymerization of styrene and is the most widely used plastic. At room temperature, the thermoplastic polymer is a solid but when heated above 100 °C it flows.

Oct 14, 2022 · Polystyrene is a versatile plastic used to make a wide variety of consumer products. It is made by polymerizing styrene, a building-block chemical used in the manufacture of many products.

May 18, 2018 · Polystyrene is a colorless, transparent thermoplastic that softens slightly above 100°C (212°F) and becomes a viscous liquid at around 185°C (365°F). It is resistant to acids, alkalies, oils, and alcohols.

Jan 6, 2019 · Learn the organic chemistry behind this very useful plastic. Why is recycling polystyrene hard? Why does polystyrene often end up as solid waste?

Feb 13, 2025 · Polystyrene is a versatile synthetic polymer that plays a crucial role in modern industries due to its affordability and unique properties. As a thermoplastic polymer, polystyrene can be melted and reshaped multiple times, making it highly adaptable for various applications across industries.
