An insulating coating material including a polyimide film, and an adhesion layer on at least one side of a polyimide film. The polyimide film has a weight of 23.5 g or less per 1 m.sup.2 and a loop stiffness value of 0.45 g/cm or more.

A distribution cabling tape comprises a resilient polymeric base sheet having a first major surface and a second major surface, the first major surface having a continuous lengthwise channel formed in a first portion thereof. The tape also includes an adhesive layer disposed on a second and third portion of the first major surface, the adhesive layer capable of adhering to a concrete or asphalt surface, such as a road, curb, or walkway.

An adhesive tape is made by providing an elongated and laminated substrate band formed by a woven fabric layer forming an outer face of the band and a flat sound-damping web forming an inner face of the band and comprised of a nonwoven, velour, or foam and then applying an adhesive coating to the inner face of the substrate band formed by the sound-damping web and also providing a marking stripe extending longitudinally of the band on the outer face of the substrate and having a coloring different from that of the woven fabric layer. Thereafter the tape is wound generally helically in succeeding overlapping turns around an elongated object with the inner face turned inward and adhering to the object and the outer face turned outward away from the object while positioning an edge of each turn along the marking strip of the preceding turn while leaving a portion of the preceding exposed.

The invention relates to a method for producing an adhesive tape (1), in particular a wrapping tape for wrapping around cables in automobiles. A strip-shaped carrier (2) is provided with a UV cross-linkable adhesive coating (5). In addition to an acrylate-based pressure-sensitive adhesive with embedded photoinitiators, the adhesive coating (5) comprises at least one additive. The photoinitiators are activated for cross-linking by irradiation with a UV light source (6) emitting in the range of its activation wavelength. According to the invention, the additive has at least in the range of the activation wavelength of the photoinitiators an absorbance (E) of 0.1 to 0.7, preferably between 0.2 and 0.6.

The invention relates to a method for producing an adhesive tape, in particular a wrapping tape to be wrapped around cables in automobiles. In said method, at least one face of a perforated support (1) is coated with an adhesive. According to the invention, a mechanically and/or chemically reinforced nonwoven fabric is used as the perforated support (1).

Method for bonding by wrapping a medium which is capable of expanding transversely to a winding with an adhesive tape, in which: an adhesive tape is unrolled from an adhesive tape roll, the unrolled adhesive tape is provided on one side of a carrier film (1) with an adhesive cement layer (2) and on an opposite side with a separating agent layer (3), the separating agent layer (3) is subjected to a plasma treatment, the plasma-treated adhesive tape is wound around the medium which is capable of expanding transversely to a winding, so that at least a portion of the adhesive tape is bonded to a lower winding ply by the adhesive cement layer (2).

The substrate for adhesive tape is thin in thickness and can also suppress repelling of a water-borne primer when the primer is being coated. The substrate for adhesive tape includes 25 to 75 parts by mass of a plasticizer and 5 to 40 parts by mass of an inorganic filler with respect to 100 parts by mass of polyvinyl chloride resin having a mean degree of polymerization of 1200 to 1800; wherein the inorganic filler has a mean particle size of 0.05 to 0.8 m; and the substrate has a thickness of 40 to 80 m.
