Foam Glossary

  • Sheet img

    Foam that is cut from a block with standard dimensions, with width 1,20m, length 2,00m and variable thickness.

  • Core img

    The interior of a mattress, topper or pillow.

  • Roll img

    Foam that is cut from a block in various thicknesses and supplied in a roll format. It can be supplied with the following lengths: 2,00m, 2,10m e 2,20m.

  • OEKO-TEX certified img

    Most of our foams are odourless and are certified OEKO-TEX®, class 1 product. This certification guarantees that the foams do not contain any chemical agent that constitutes a health risk, guaranteeing the safety of their use.

  • Compression set img

    Also known as static fatigue, compression set measures the loss of thickness of a foam sample, as a percentage, after prolonged compression.

  • Curing warehouse img

    Place where foam is stored after production. The curing process allows the foam to achieve its final properties. The curing time can vary between 48h (conventional and high resilience foams) and 72h (viscoelastic foams).

  • Density img

    Is measured in kg/m3 and refers to the mass (weight) of the foam per unit of volume.

  • Hardness img

    Refers to the resistance that the foam offers to penetration and compression to which it is submitted. It is measured in kilo Pascals (kPa) or Newtons (N).

  • Elongation img

    Property of the foam analysed in a test in which a foam sample of specific dimensions is stretched, until its rupture.

  • Foam img

    Polyurethane foam results from a reaction between a polyol and an isocyanate with a polymeric three-dimensional structure.
    Polyurethane foams are divided into 3 types: rigid, flexible and moulded foams. They can be soft or hard, more or less resilient, produced in different colours or infused with additives that give them special characteristics.

  • Conventional foam img

    The most used in the industry, giving a balance between support and comfort to the products where it is applied.

  • Viscoelastic foam img

    Formulated to provide greater pressure absorption, which makes it the best comfort option. It has low resilience, moulding to any shape and body weight and returning to its original shape after compression. Viscoelastic foam reacts to heat and weight.

  • High resilience foam img

    The most resilient type of flexible polyurethane foam. What sets it apart is its quick recovery capacity when subjected to a compression, by return immediate energy it provides.

  • Cellular structure of foam img

    Structure that is constituted by cells, surrounded by the polymeric structure of foam.

  • Polymeric structure img

    The matrix of a foam, formed by the bonds of its chemical components.

  • Isocyanates img

    Organic compounds that contain a cyanate group (N=C=O); at Eurospuma we use TDI and MDI.

  • kPa img

    Pressure unit (kiloPascal).

  • MDI img

    Methylene diphenyl diisocyanate.

  • Polyurethane img

    Polymeric material that results from the reaction of polyols and isocyanates, causing a repetition in the chain of an organic compound.

  • img

    Compound that contains an (-OH) bond, also known as alcohol, used when formulating foam.

  • Resilience img

    Determines the energy returned by it after an impact or compression. The value of this property is obtained by testing the ball bounce, which consists of dropping a steel ball (in free fall), from a predetermined height, on a foam sample.

  • TDI img

    Toluene diisocyanate.
