Why use nonwovens in electrics and electronics?

The structure of nonwovens gives strength and elasticity. Nonwovens insulating tape can therefore stand the stress applied during the wrapping process as well as that which arises from varying degrees of cable dimension and flexibility in use.

Different uses are:

Power cables
Communications cables

Industrial cables
Fuel cells
Battery separators
Cable wrapping

For example:

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.

‘Power Paper’ is based on cellulose fibres, broken down by hydroentanglement at the nanocellulose pilot facility of forestry products developer?to become as thin as 20 nm in diameter. With the cellulose fibres in a solution of water, an electrically charged polymer, also provided in a water solution, is added. The polymer then forms a thin coating around the fibres.
