A thermally vulcanizable pressure-sensitive adhesive, comprising a chemically precrosslinked, pressure-sensitive polybutadiene polyurethane and ground sulfur, which remains tacky during the heating phase, does not liquefy and thus in this phase, in which the vulcanization has not yet started and the curing has not yet begun, at least under low to medium load is shear strength, can transmit forces and thus achieve a holding power, a process for its preparation, an adhesive tape containing this pressure-sensitive adhesive and a method for producing the adhesive tape. |
