  2. Styrofoam - Wikipedia

    en.wikipedia.org/wiki/Styrofoam

    Styrofoam insulation extruded polystyrene foam (XPS), owned and manufactured by DuPont. Styrofoam is a genericized trademarked brand of closed-cell extruded polystyrene foam (XPS), manufactured to provide continuous building insulation board used in walls, roofs, and foundations as thermal insulation and as a water barrier.

  3. Polystyrene - Wikipedia

    en.wikipedia.org/wiki/Polystyrene

    Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3. [47] It is usually white and made of pre-expanded polystyrene beads. The manufacturing process for EPS conventionally begins with the creation of small polystyrene beads.

  4. Phase-out of polystyrene foam - Wikipedia

    en.wikipedia.org/wiki/Phase-out_of_polystyrene_foam

    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.

    Rigid cellular polystyrene (RCPS). This includes extruded polystyrene foam XPS (such as Styrofoam and commonly referred to as "blue board," expanded polystyrene foam EPS (commonly referred to as "beadboard"), and MEPS. Polyisocyanurate (also known as polyiso). More stable at high temperatures and less flammable than polyurethane.

    "This can insulate better than most other current thermal insulators, including Styrofoam," Tian Li, a researcher on the project, said in a statement. "It is extremely promising to be used as ...

  7. Foam food container - Wikipedia

    en.wikipedia.org/wiki/Foam_food_container

    Foam take-out containers are made from expanded polystyrene (EPS) foam, or another type of polystyrene foam, and produced by injecting the foam into a mold. They are usually white in color, although they may be printed or impressed with a company logo or other message. EPS foam is sometimes incorrectly called Styrofoam as a generic term.

  8. Building insulation material - Wikipedia

    en.wikipedia.org/wiki/Building_insulation_material

    Open-cell foam is porous, allowing water vapor and liquid water to penetrate the insulation. Closed-cell foam is non-porous, and not moisture-penetrable, thereby effectively forming a semi-permeable vapor barrier. (N.B., vapor barriers are usually required by the Building Codes, regardless of the type of insulation used.
