This product wraps cables with a PVC cover combined to an EMC conductive element, to protect the cables from environment, from EM/RF interferences and to keep cables bundled together.
There are several different closures like Velcro, Zipper, buttons, etc..
A PVC cover is laminated with Al foil to provide higher EMI noise shielding. Some are available with additional layers of shielding material such as conductive mesh, conductive fabric, to enhance the shielding performance.
