2. Styrofoam - Wikipedia

   en.wikipedia.org/wiki/Styrofoam

   The claimed R-value of Styrofoam insulation is approximately 5 °F⋅ft 2 ⋅h/BTU for 1 inch thick sheet. [7] Styrofoam can be used under roads and other structures to prevent soil disturbances due to freezing and thawing. [8] [9] DuPont also produces Styrofoam blocks and other shapes for use by florists and in craft products. [10]

3. Structural insulated panel - Wikipedia

   EPS is the most common of the foams used and has an R-value (thermal resistance) of about 4 °F·ft 2 ·h/Btu (equivalent to about 0.7 K·m 2 /W) per 25 mm thickness, which would give the 3.5 inches (89 mm) of foam in a 4.5-inch-thick (110 mm) panel an R value of 13.8 (caution: extrapolating R-values over thickness may be imprecise due to non ...

   Sheets of EPS are commonly packaged as rigid panels (common in Europe is a size of 100 cm x 50 cm, usually depending on an intended type of connection and glue techniques, it is, in fact, 99.5 cm x 49.5 cm or 98 cm x 48 cm; less common is 120 x 60 cm; size 4 by 8 ft (1.2 by 2.4 m) or 2 by 8 ft (0.61 by 2.44 m) in the United States). Common ...

   In 2019, the European Parliament voted 560 to 35 to ban all food and beverage containers made from expanded polystyrene throughout the European Union member states. [2] Canada amended its 'Canadian Environmental Protection Act, 1999' in 2022 to prohibit foodservice ware made of expanded or extruded polystyrene, and also polyvinyl chloride ...

   Styrene is an organic compound with the chemical formula C 6 H 5 CH=CH 2.Its structure consists of a vinyl group as substituent on benzene.Styrene is a colorless, oily liquid, although aged samples can appear yellowish.

7. Aluminium foam sandwich - Wikipedia

   After which this three-layer composite is heated to transform the core layer into foam. [2] [9] The melting point of the face sheet material is above the melting point of the foamable precursor material. The precursor composition is usually Al-Si, Al-Si-Cu or Al-Si-Mg alloys while the face sheets are 3xxx, 5xxx and 6xxx series aluminium alloys.
