2. Pull buoy - Wikipedia

   en.wikipedia.org/wiki/Pull_buoy

   Pull buoy. A pull buoy or leg float is a figure-eight shaped piece of closed-cell foam used in swim workouts. Swimmers place the buoy between their thighs or their ankles to provide support to the body without kicking their legs; this allows the swimmer to focus on training only their arms [1] and developing both endurance and upper body strength.

3. Metal foam - Wikipedia

   en.wikipedia.org/wiki/Metal_foam

   Open-cell metal foam CFD (numerical) simulation of fluid flow and heat transfer on an open cell metal foam. Open-celled metal foam, also called metal sponge, [3] can be used in heat exchangers (compact electronics cooling, cryogen tanks, PCM heat exchangers), energy absorption, flow diffusion, CO 2 scrubbers, flame arrestors, and lightweight optics. [4]

4. 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.

5. Sandwich-structured composite - Wikipedia

   en.wikipedia.org/wiki/Sandwich-structured_composite

   Recycled paper is also now being used over a closed-cell recycled kraft honeycomb core, creating a lightweight, strong, and fully repulpable composite board. This material is being used for applications including point-of-purchase displays, bulkheads, recyclable office furniture, exhibition stands, wall dividers and terrace boards.

6. Syntactic foam - Wikipedia

   en.wikipedia.org/wiki/Syntactic_foam

   Syntactic foam, shown by scanning electron microscopy, consisting of glass microspheres within a matrix of epoxy resin. Syntactic foams are composite materials synthesized by filling a metal, polymer, [1] cementitious or ceramic matrix with hollow spheres called microballoons [2] or cenospheres or non-hollow spheres (e.g. perlite) as aggregates.

7. Closed-cell PVC foamboard - Wikipedia

   en.wikipedia.org/wiki/Closed-cell_PVC_foamboard

   Closed-cell PVC foam takes solid shape due to its linear structure. However, due to this structure, it is more brittle than open-celled PVC foam. It is available in densities varying from 3 to 25 pounds per cubic foot (0.048 to 0.400 g/cm 3). [3] It has a low flammability rate. [4]

9. Aluminium foam sandwich - Wikipedia

   en.wikipedia.org/wiki/Aluminium_foam_sandwich

   Ex-situ bonding is achieved by gluing face sheets with an aluminium foam by adhesive bonding, brazing or diffusion bonding. Foams used in this method are either closed-cell or open-cell. When a closed-cell foam is used then it is produced from aluminium alloys either by liquid metal route (e.g. Alporas, [3] Cymat [4]) or by powder metallurgy [2 ...
