    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 ...

    en.wikipedia.org/wiki/Rigid_panel

    Rigid panel insulation, also referred to as continuous insulation, [1] can be made from foam plastics such as polyurethane (PUR), polyisocyanurate (PIR), and polystyrene, or from fibrous materials such as fiberglass, rock and slag wool. Rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus ...

    Trailer skirts comprise a pair of panels affixed to the lower side edges of a trailer, running most of the length of the trailer and filling the gap between the forward and rear axles. Trailer skirts are typically constructed of aluminum , plastic , or fiberglass , with plastic the most resistant to damage from side or bottom impacts. [ 2 ]

    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.

    en.wikipedia.org/wiki/Ballistic_foam

    The density of the foam varies with the type being used; Type 2.5 is a white to light amber foam weighing 2.5 pounds per cubic foot, while Type 1.8 is a pale blue to green foam weighing 1.8 pounds per cubic foot. [3] Chopped fiberglass strands embedded in the foam add to the structural integrity through physical support and shrapnel mitigation.

  7. Polyimide foam - Wikipedia

    en.wikipedia.org/wiki/Polyimide_foam

    Polyimide foam is a foam originally designed for NASA by Inspec Foams Inc. under the brand name Solimide. [1] Its primary purposes are as an insulator (such as for rocket fuels ) and acoustic damper.

  8. Firefighting foam - Wikipedia

    en.wikipedia.org/wiki/Firefighting_foam

    Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, thus achieving suppression of the combustion. Firefighting foam was invented by the Moldovan engineer and chemist Aleksandr Loran in 1902. [1] The surfactants used must produce foam in concentrations of ...

  9. Building insulation material - Wikipedia

    en.wikipedia.org/wiki/Building_insulation_material

    Rigid panel insulation, also known as continuous insulation [13] can be made from foam plastics such as polyisocyanurate or polystyrene, or from fibrous materials such as fiberglass, rock and slag wool. Rigid panel continuous insulation is often used to provide a thermal break in the building envelope, thus reducing thermal bridging.
