2. Expanded polyethylene - Wikipedia

   en.wikipedia.org/wiki/Expanded_polyethylene

   EPE foams are low density, semi-rigid, closed cell foam that are generally somewhere in stiffness/compliance between Expanded polystyrene and Polyurethane. Production of EPE foams is similar to that of expanded polystyrene, but starting with PE beads. [1] Typical densities are 29 to 120 kg/m 3 (49 to 202 lb/cu yd) with the lower figure being ...

3. Polymeric foam - Wikipedia

   A polymeric foam is a special foam, in liquid or solidified form, formed from polymers. [1] Examples include:

4. Foam rubber - Wikipedia

   en.wikipedia.org/wiki/Foam_rubber

   Foam rubber was first made in 1929, by E. A. Murphy [2] and Eric Owen, two research chemists at Dunlop Rubber, who used whipped latex. In 1937, isocyanate-based materials were first used to make foam rubber. After World War II, styrene-butadiene rubber replaced many natural types of foam. Foam rubber has been used commercially for a wide range ...

5. Structural insulated panel - Wikipedia

   en.wikipedia.org/wiki/Structural_insulated_panel

   The third component in SIPs is the spline or connector piece between SIPs. Dimensional lumber is commonly used but creates thermal bridging and lowers insulation values. To maintain higher insulation values through the spline, manufacturers use Insulated Lumber, Composite Splines, Mechanical Locks, Overlapping OSB Panels, or other creative methods.

6. Low-density polyethylene - Wikipedia

   en.wikipedia.org/wiki/Low-density_polyethylene

   LDPE has SPI resin ID code 4 Schematic of LDPE branching structure. Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene.It was the first grade of polyethylene, produced in 1933 by John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. [1]

7. Phase-out of polystyrene foam - Wikipedia

   en.wikipedia.org/wiki/Phase-out_of_polystyrene_foam

   Animals do not recognize polystyrene foam as an artificial material, may mistake it for food, and show toxic effects after substantial exposure. Full or partial bans of expanded and polystyrene foam commonly target disposable food packaging. Such bans have been enacted through national legislation globally, and also at sub-national or local ...

8. Polyolefin - Wikipedia

   en.wikipedia.org/wiki/Polyolefin

   IKEA's Better Shelter uses structural panels made out of polyolefin foam, stating, "They are tough and durable.". [17] Piping systems for the conveyance of water, chemicals or gases are commonly produced in Polypropylene, and to a much greater extent Polyethylene. Piping systems in high-density Polyethylene (HDPE, PE100, PE80) are fast becoming ...

9. Ethylene-vinyl acetate - Wikipedia

   EVA is one of the materials popularly known as expanded rubber or foam rubber. EVA foam [ 3 ] [ 4 ] [ 5 ] is used as padding in equipment for various sports such as ski boots , bicycle saddles, hockey pads, boxing and mixed-martial-arts gloves and helmets, wakeboard boots, waterski boots, fishing rods , and fishing-reel handles.
