The raw materials used have a great deal of influence on the material’s properties.
Material type
tape
Type of finishing
with copper foil top layer
Color
black
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.
Possibilities Material
Most sold thicknesses
1,2 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.
Max width of rolls
1000 mm
We produce strips and shapes from rolls of material. The standard roll width indicates the possibilities with respect to maximum dimensions.
UV resistance
very good
Ozone resistance
very 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
-40 °C to +90 °C, intermittent +100 °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.
DIN 4102 part 1
B2
Application temperature
> 5 °C
Water vapor permeability
sd > 1200m (DIN 4108-3)
Damp diffusion
μ > 1.000.000 (DIN 52615)
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
1 year
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%.
