Wiring Harness Tape for Bundling and Protection

Wiring harness tape bundles cables and, depending on the product and installation location, can protect them from mechanical wear or unwanted noise. A PET nonwoven tape designed for vehicle interiors can bundle cables, wrap flexibly and damp noise. These properties do not automatically apply to every tape in the category. First define what the wrap needs to do on the harness, then check the construction of the specific item.

Nonwoven tape is an option when the wrap needs to bundle cables, remain flexible or damp noise. A PET/cellulose nonwoven tape combines these functions on wiring harnesses in vehicle interiors. Unwind behaviour and handling during manual wrapping also matter when choosing a tape. For other installation locations or stresses, the properties of the selected product determine whether it fits; the backing material alone does not establish suitability for your application.

The difference starts with the backing construction and the job the wrap needs to do. PET nonwoven tapes can be used for bundling and noise damping, while PET fabric tapes can be used for cable bundling and wrapping points exposed to wear. There is no general ranking: abrasion, flexibility, unwind behaviour and installation location have to be checked for the specific product. Include these requirements in your enquiry so the choice is based on more than the material name.

No. Bundling a wiring harness does not mean the tape provides electrical insulation. Electrical insulation tapes, shielding tapes and harness wraps serve different purposes. Whether a tape insulates electrically depends on the properties of the specific product. If electrical insulation is required, state that requirement explicitly and check the relevant product data instead of inferring the property from use on a cable.
