    en.wikipedia.org/wiki/Polystyrene

    Polystyrene (PS) / ˌ p ɒ l i ˈ s t aɪ r iː n / 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 ...

    Expanded polystyrene, often termed Styrofoam, is a contributor of microplastics from both land and maritime activities. Polystyrene is not biodegradeable but is susceptible to photo-oxidation, and degrades slowly in the ocean as microplastic marine debris. Animals do not recognize polystyrene foam as an artificial material, may mistake it for ...

    Polystyrene (PS) Polyurethanes (PUR) and PP&A fibers [15] are often also included as major commodity classes, although they usually lack RICs, as they are chemically quite diverse groups. These materials are inexpensive, versatile and easy to work with, making them the preferred choice for the mass production everyday objects. Their biggest ...

    6: polystyrene (PS) (plastic utensils, Styrofoam, cafeteria trays, etc.) 7: Other (N/A) other plastics, such as acrylic, nylon and polycarbonate. When a number is omitted, the arrows arranged in a triangle resemble the universal recycling symbol, a generic indicator of recyclability. Subsequent revisions to the RIC have replaced the arrows with ...

    Atactic polymers such as polystyrene (PS) are technologically very important. [citation needed] If a special catalyst [clarification needed] is used in its synthesis, it is possible to obtain the syndiotactic version of this polymer, but most industrial polystyrene produced is atactic.

    "Styrofoam" is a special form of polystyrene trademarked by the Dow Chemical Company.) Just because foam peanuts were originally made by Dow Chemical does not mean they are made out of "styrofoam" (tm). Styrofoam, still made by Dow Chemical, is typically blue and it is put on the sides of houses for insulation purposed.
