  2. Natural oil polyols - Wikipedia

    en.wikipedia.org/wiki/Natural_oil_polyols

    One of the first uses for NOPs (other than castor oil) was to make spray-on polyurethane foam insulation for buildings. [17] NOPs are also finding use in polyurethane slab foam used to make conventional mattresses [8] as well as memory foam mattresses. [18] [19] The characteristics of NOPs can be varied over a very wide range.

  3. Biofoam - Wikipedia

    en.wikipedia.org/wiki/Biofoam

    A foam is considered open-celled if at least two of its facets are holes rather than walls. [18] In this case the entirety of the load on the foam is on the cross-beams that make up the edges of the cell. [6] If no more than one of the walls of the cell are holes, the foam is considered closed-celled in nature. [18]

    en.wikipedia.org/wiki/Bio-based_building_materials

    Building impacts belong to two distinct but interrelated types of carbon emissions: operational and embodied carbon.Operational carbon includes emissions related to the building's functioning, such as lighting and heating; embodied carbon encompasses emissions resulting from the physical construction of buildings, including the processing of materials, material waste, transportation, assembly ...

  5. 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 ...

  6. 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.

  7. Bio-based material - Wikipedia

    en.wikipedia.org/wiki/Bio-based_material

    A bio-based material is a material intentionally made, either wholly or partially, from substances derived from living (or once-living) organisms, [1] such as plants, animals, enzymes, and microorganisms, including bacteria, fungi and yeast.

  8. Hempcrete - Wikipedia

    en.wikipedia.org/wiki/Hempcrete

    The material has low mechanical properties and low thermal conductivity, making it ideal for insulation material. Hempcrete blocks have a low carbon footprint and are effectively carbon sinks. Widespread codes and specifications still need to be developed for the widespread usage of hempcrete, but it shows promise to replace current non-bearing ...

  9. Ecovative Design - Wikipedia

    en.wikipedia.org/wiki/Ecovative_Design

    Ecovative was developed from a university project of founders Eben Bayer and Gavin McIntyre. In their Inventor's Studio course at Rensselaer Polytechnic Institute taught by Burt Swersey, Eben and Gavin developed and then patented a method of growing a mushroom-based insulation, initially called Greensulate before founding Ecovative Design in 2007.
