2. List of polyurethane applications - Wikipedia

   en.wikipedia.org/wiki/List_of_polyurethane...

   Industrial Insulation. Rigid polyurethane foam is used in various industries to provide thermal insulation to installations and pipes. In particular, the piping for district heating systems in Europe is primarily insulated using a pre-insulated pipes sandwich assembly composed of a steel heat service pipe, an insulating layer (polyurethane foam) and a polyethylene (PE) casing, which are bonded ...

3. Polyurethane foam - Wikipedia

   en.wikipedia.org/wiki/Polyurethane_foam

   An assortment of polyurethane foam products for cushioning and insulation. Polyurethane foam is a solid polymeric foam based on polyurethane chemistry. As a specialist synthetic material with highly diverse applications, polyurethane foams are primarily used for thermal insulation and as a cushioning material in mattresses, upholstered furniture or as seating in vehicles.

4. Foam rubber - Wikipedia

   en.wikipedia.org/wiki/Foam_rubber

   Foam rubber (also known as cellular rubber, sponge rubber, or expanded rubber) is rubber that has been made with a foaming agent so that its structure is an air-filled matrix. Commercial foam rubber is generally made of synthetic rubber , natural latex , or polyurethane .

5. Reticulated foam - Wikipedia

   en.wikipedia.org/wiki/Reticulated_foam

   Robert A. Volz is credited with discovering the first process for making reticulated polyurethane foam in 1956 while working for the Scott Paper Company. [6] Production of reticulated polyurethane foam is a two-step process that begins with the creation of conventional (closed-cell) polyurethane foam, after which cell faces (or "windows") are removed.

6. Duct (flow) - Wikipedia

   en.wikipedia.org/wiki/Duct_(flow)

   There are various types of rigid polyurethane foam panels available, including water formulated panel for which the foaming process is obtained through the use of water and CO 2 instead of CFC, HCFC, HFC and HC gasses. Most manufacturers of rigid polyurethane or phenolic foam panels use pentane as foaming agent instead of the aforementioned gasses.

7. Lost-foam casting - Wikipedia

   en.wikipedia.org/wiki/Lost-foam_casting

   Lost-foam casting (LFC) is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of polymer foams to simplify the investment casting process by removing the need to melt the wax out of the mold.

8. Nonwoven fabric - Wikipedia

   en.wikipedia.org/wiki/Nonwoven_fabric

   Multiple colored swatches of non-woven fabric. Nonwoven fabric or non-woven fabric is a fabric-like material made from staple fibre (short) and long fibres (continuous long), bonded together by chemical, mechanical, heat or solvent treatment.

9. 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.
