Why use nonwovens in electrics and electronics？
Thanks to nonwovens a water-blocking tape can be designed to be conductive or non-conducive and is impregnated with a powder which expands on contact with water. The expansion prevents water seeping along the cable.
The high porosity which can be achieved in nonwovens is an important factor, as a thermal barrier can be established by means of air trapped between fibres. Conductivity can be obtained by carbon impregnation of the porous structure.
