Expanded polystyrene packaging A polystyrene yogurt container Bottom of a vacuum-formed cup; fine details such as the glass and fork food contact materials symbol and the resin identification code symbol are easily molded. 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 ...
Fire-safe polymers are polymers that are resistant to degradation at high temperatures. There is need for fire-resistant polymers in the construction of small, enclosed spaces such as skyscrapers, boats, and airplane cabins. [1] In these tight spaces, ability to escape in the event of a fire is compromised, increasing fire risk.
Fire-retardant materials should not be confused with fire-resistant materials. A fire resistant material is one which is designed to resist burning and withstand heat. An example of a fire-resistant material is one which is used in bunker gear worn by firefighters to protect them from the flames of a burning building.

In the event of a fire this draws hot air up like a chimney, intensifies the fire, and spreads it to the top of the clad area. The fire can then get inside the building through open windows, for example to curtains blowing through windows. [1] In addition to the chimney effect, the cladding material itself can contribute to a fire.
Class II, Semi-impermeable (0.1-1 US perm, or 5.7-57 SI perm) – such as unfaced expanded or extruded polystyrene, OSB, fiber-faced isocyanurate, 30 pound asphalt-impregnated building papers, exterior oil-based paints, unfaced expanded polystyrene, 30 pound asphalt coated paper, plywood, bitumen coated kraft paper;

Discarded polystyrene cup on the shore of Lake Michigan. In the late 20th and early 21st century, there has been a global movement towards the phase-out of polystyrene foam as a single use plastic (SUP). Early bans of polystyrene foam intended to eliminate ozone-depleting chlorofluorocarbons (CFCs), formerly a major component.
