Nonwoven products are used for various insulation and protective applications in the electronics industry.
Production methods, raw materials and finish can all be chosen for their mechanical, physical and chemical properties to provide the perfect solution for different types of cable wrapping.
The structure of nonwovens gives strength and elasticity. Nonwoven 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.
Thanks to nonwovens a water-blocking tape can be designed to be conducive or non-conducive and is impregnated with a power 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 obtainded by carbon impregnation of the porous structure.
Some examples of where nonwovens are used
- Power cables
- Communications cables
