ADHESIVE TAPE
The invention relates to an adhesive tape with a carrier composed of a film, there being applied on one side of the carrier an adhesive based on natural rubber or synthetic rubber, where the film is a biaxially oriented film made of polypropylene, polyethylene or polyester such as PET, and on the side of the carrier not coated with adhesive there is a release layer, based in particular on carbamate.
1 . Adhesive tape with a carrier composed of a film, there being applied on one side of the carrier an adhesive based on natural rubber or synthetic rubber, where
the film is a biaxially oriented film made of polypropylene, polyethylene or polyester, and on the side of the carrier not coated with adhesive there is a release layer, based on carbamate.
2 . Adhesive tape according to claim 1 ,
wherein
the draw ratio on drawing of the film in longitudinal direction is 1:5 to 1:9, and/or
the draw ratio on drawing of the film in transverse direction is 1:5 to 1:10.
3 . Adhesive tape according to claim 1 ,
wherein
the draw ratio on drawing of the film in longitudinal direction (machine direction) is 1:3.5 to 1:6, and/or
the draw ratio on drawing of the film in the transverse direction is 3.5 to 1:6, and/or
the draw ratio on drawing of the film is the same in longitudinal and transverse directions.
4 . Adhesive tape according to claim 1 ,
wherein
the adhesive tape has fibre-like reinforcing materials, which are mounted directly on the film, incorporated into the film or incorporated into the adhesive.
5 . Adhesive tape according to claim 1 ,
wherein
the adhesive tape has a film carrier having a thickness of between 30 and 55 μm.
6 . Adhesive tape according to claim 1 ,
wherein
an adhesion promoter is applied between carrier and layer of adhesive.
7 . Adhesive tape according to claim 1 ,
wherein
the adhesive is selected from the group consisting of the natural rubbers or of the blends of natural rubbers and synthetic rubbers.
8 . Adhesive tape according to claim 1 ,
wherein
the adhesive comprises tackifier resins.
9 . Adhesive tape according to claim 1 ,
wherein
the adhesive comprises at least one UV protectant and/or other blending components.
