    Product attributes

    General Description
    Raw material
    PE
    The raw materials used have a great deal of influence on the material’s properties.
    Material type
    foam
    A material is a naturally or artificially produced substance that is to be further processed into semi-finished or finished products. The right material can be chosen based on the properties needed for your application. Important properties include hardness, elasticity, durability and cost.
    Finishing: foam
    non-cross linked
    Color
    white
    Most of our product range comes in black, grey or white. We can also supply materials in other colours, such as red, yellow, green or blue. Please bear in mind that there is always some tolerance with respect to colour. The degree of tolerance varies between materials and is greater in some than in others.
    Cell structure
    closed cell
    The cell structure indicates whether a material is open, semi-closed or closed. In materials with a closed cell structure, all cells are closed and the air cannot escape the cells. Materials with a closed cell structure can generally only be compressed by a certain percentage before the cells burst and the material disintegrates. By contrast, the air in materials with an open cell structure can enter and leave the cells. For this reason, open-celled materials can usually be completely compressed. Semi-closed materials fall between these two types. If the material is not compressed, air can circulate through it to a limited extent. But once the material is compressed by a certain percentage, the cells close and the material becomes closed in structure.
    Density
    28 kg/m³
    A material’s compactness or density expresses the mass of that material present in a given volume. For most of our products, this is expressed in kg/m³. The manufacture of any given material always allows for tolerance on density. This cannot be avoided, unfortunately, but it is accurately tracked in quality controls. We measure the density or specific gravity of materials in accordance with international standards. This enables materials to be more effectively and accurately compared.
    Density range and norm
    25 to 31 kg/m³ (DIN EN ISO 845)
    Possibilities Material
    Self adhesive possibilities
    1 side, 2 sides, without adhesive
    The self-adhesive options depend on the properties, shape and intended application of the material. We can supply most materials unglued (without a self-adhesive side), with one self-adhesive side, and with two self-adhesive sides. However, some materials cannot have glue applied to them, and there are some profiles that we can only supply with one self-adhesive side.
    Most sold thicknesses
    10, 15, 20, 25, 30, 40, 50 mm
    While the most commonly sold thicknesses provide an initial indication of the standard options available, there are many more possibilities. If the thickness you are looking for is not listed, please contact us. We can often can easily customise the thickness, and there may also be an alternative material that comes in the desired thickness.
    Minimum thickness
    5 mm
    The minimum thickness gives an indication of our technical capabilities, and is often a standard thickness. Should you need thinner material, however, please contact us. Sometimes we can provide this, and other times we can supply alternative materials in the desired thickness.
    Maximum thickness
    100 mm
    The maximum thickness gives an indication of our technical capabilities. Should you need thicker material, however, please contact us. For some materials, we can glue several layers together to achieve the desired thickness, while for other materials we can use larger blocks. The possible solutions usually depend on the other desired dimensions and shape.
    Non standard thicknesses
    easily created by splitting blocks
    If you want a material in a non-standard thickness, we can usually help you very quickly. For many materials, we make our own sheets and rolls in any desired thickness. We peel the desired thickness from master blocks, and can do so with a short delivery time. For materials where we cannot do this ourselves (by request for larger quantities), we can often give a quick answer as to whether we are able to meet the request.
    Dimension sheet
    1200 x 2000 mm
    At EKI, we cut shapes and strips from sheets. The standard sheet width indicates the maximum dimensions that are possible.
    UV resistance
    good
    Ozone resistance
    good
    Sealing for which joint types
    level/parallel
    flat = smooth surface like metal/uneven = irregular surface like masonry/parallel = a joint that is very constant/gradient = a joint that varies a lot in thickness. Smooth and flat joints are not a problem, but irregular and gradient joints can be challenging. When it comes to masonry, for example, any unevenness should be properly accommodated but still provide a good seal. For gradient joints, the material should be very compressible, but still provide an effective seal in the areas where the tape is much less compressed.
    Technical Properties Material
    Temperature range
    -30 °C to +70 °C, intermittent +80 °C
    FMVSS302
    compliant
    The Federal Motor Vehicle Safety Standard (FMVSS) 302 is an international test that measures the flammability of a material. This standard specifies the burning behaviour exhibited by a material. If a material is compliant, this means that a certain minimum level of safety is guaranteed.
    Linear shrinkage 22h, 70 °C
    < 5%
    Thermal conductivity
    0,037 W/mK
    Thermal conductivity indicates how a material conducts heat, and depends on temperature, density and moisture content. This value is calculated at 20°C
    Water absorption
    < 1% (DIN 53428)
    Tensile strength kPa
    220 kPa (> 175 kPa, DIN EN ISO 1798)
    How much force must be applied before a material breaks? Tensile strength is a measure for classifying a material’s mechanical properties. The tensile strength limit value indicates the minimum amount of force or stress a material can withstand before it breaks.
    Elongation
    140% (> 120%, DIN EN ISO 1798)
    The elongation is a measure of the material’s elasticity, and relates to its tensile strength. It indicates the percentage by which the material is elongated when the specified force of tensile strength is used. The elongation is expressed as a percentage of the original length: 120% means that the material can be stretched by 20% of its original size before it breaks.
    Maximum % of compression
    50%
    This indicates the maximum percentage by which a material can be compressed without breaking the material. For example, if closed-cell foam is compressed by more than 50%, the cells burst. The maximum compression percentage for harder materials is much lower. Very soft materials with an open cell structure can often be almost completely compressed.
    Applications, Standards
    REACH
    compliant
    REACH is a European regulation that deals with which chemical substances should not be included in materials. The main idea behind it is the improved protection of human and environmental health from the risks of chemicals. This list of substances is regularly modified and expanded, and EKI monitors this on an ongoing basis.
    RoHS
    compliant
    The RoHS (Restriction of Hazardous Substances) directive is concerned with limiting the use of hazardous substances in electrical and electronic equipment. This standard is therefore mainly used in the electrical industry and is regularly updated. EKI monitors this on an ongoing basis.
    Recyclable
    compliant
    We are already recycling residual waste from our production process as much as possible. In most cases, this means grinding the rubber or foam into small pellets that are then reused as the basis for new products. If customers return residual waste, EKI includes it in this recycling process.
    CFC and HCFC free
    compliant
    In short, the material is ozone-friendly. We get this question regularly at EKI, especially from sealant companies. Although the question is more applicable to some materials than to others, we have extended this notion throughout our entire range.
    Shelf life
    2 years
    The amount of time a material may remain in stock after it has come in, before being used. This is based on an assumption of normal indoor conditions, and that the material is still in its original packaging. Our guideline is a temperature of 20°C and relative humidity of 40% to 50%.
    HS code
    3901101090
    HS (Harmonized System) code is an international standard for categorising goods, and is mainly used for export purposes.
