2. Spray foam - Wikipedia

   en.wikipedia.org/wiki/Spray_foam

   Polyurethane is a closed-cell foam insulation material that initially contains a low-conductivity gas in its cells. [6] As a result of the high thermal resistance of the gas, spray polyurethane insulation typically has an initial R-value around R-3.4 to R-6.7 per inch. [ 6 ]

3. Package cushioning - Wikipedia

   en.wikipedia.org/wiki/Package_cushioning

   This includes expanded polystyrene foam pieces (foam peanuts), similar pieces made of starch-based foams, and common popcorn. The amount of loose fill material required and the transmitted shock levels vary with the specific type of material. [2] Paper Paper can be manually or mechanically wadded up and used as a cushioning material.

4. Foam peanut - Wikipedia

   en.wikipedia.org/wiki/Foam_peanut

   Foam peanuts (made of expanded polystyrene) The inner structure of a foam peanut, magnified 390× on an SEM. Foam peanuts, also known as foam popcorn, packing peanuts, or packing noodles, are a common loose-fill packaging and cushioning material used to prevent damage to fragile objects during shipping. They are shaped to interlock when ...

5. Expanded polyethylene - Wikipedia

   en.wikipedia.org/wiki/Expanded_polyethylene

   Polyethylene bead foams (including) EPE can be used to replace both polystyrene foam, and both rigid and flexible polyurethane. Uses include cushioning applications, and impact absorption applications including packaging. [4] Consumption of polyethylene for PE foam was estimated at 114x10 6 kg in 2001. The majority was used for non-crosslinked ...

   Solid polymeric foam for packaging under the optical microscope. A polymeric foam is a special foam, in liquid or solidified form, formed from polymers. [1]Examples include:

8. Polystyrene - Wikipedia

   en.wikipedia.org/wiki/Polystyrene

   Although it is a closed-cell foam, both expanded and extruded polystyrene are not entirely waterproof or vapor proof. [58] In expanded polystyrene there are interstitial gaps between the expanded closed-cell pellets that form an open network of channels between the bonded pellets, and this network of gaps can become filled with liquid water.

9. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   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. Check with the local authorities to find out the requirements for your area.) Closed-cell foams are superior insulators.
