Abstract

The invention provides an adhesive tape with a strap-shaped substrate material, which is used for wrapping a longitudinally extending object, particularly a conductor bundle or cable bunch. At least one side of the substrate material is spread with a special pressure-sensitive adhesive. The tape is characterized in that: the substrate material is formed by embossed PVC thin films; and the embosseddepth is 0.01 to 8mum, preferably 0.1 to 3mum.

Description

technical field [0001] The present invention relates to an adhesive tape, especially an adhesive tape used for insulating and wrapping wires or cables, which has a base material coated with glue on one or both sides; Motor vehicles such as automobiles) wire and cable applications. Background technique [0002] Insulating tapes and cable wrapping tapes usually consist of plasticized PVC film coated on one side. Tapes of this type based on soft PVC films are also used in automobiles to wrap electrical conductors into cable harnesses. If improved electrical insulating properties were initially important for tapes originally developed as insulating tapes, the tapes must now perform additional functions, such as bundling and permanently fixing several individual cables into more stable cable bundles , or protect the cable from mechanical, thermal and chemical environmental impacts. [0003] Even today, the vast majority of such cable bundles are wrapped by hand. However, when...
