Beschreibung
Zusammenfassung:	Insulating adhesive tapes for covering articles, in particular pipes placed in the soil and exposed to shearing stress, electric polarization and elevated temperatures, comprise a coating or layer of an adhesive mixture containing, by weight, 20 to 60% of synthetic and/or natural rubber, 2 to 20 % of an adhesion-improving material (e.g. a hydrocarbon resin) and optionally vulcanization-inducing materials, 3 to 30 % of an insulation-modifying material (e.g. an olefin polymer or copolymer or bitumen) and 30 to 70 % of fillers and auxiliaries, applied to a carrying foil (e.g. of PVC or polyethylene) optionally with the insertion of an adhesion-transmitter layer.
