  • Patent number: 12221570
    Abstract: A process for producing a cured pressure-sensitive adhesive that comprises a composition including at least one solid acrylonitrile-butadiene rubber, at least one tackifier resin, and optionally at least one liquid acrylonitrile-butadiene rubber, comprises subjecting the composition to electron-beam irradiation (EBC) with an acceleration voltage of 1.8 to 2.38 kV per 1 pm layer thickness of the composition and with a total beam dose of 5 to 50 kGy. Also disclosed is a cured pressure-sensitive adhesive obtained or obtainable by the process. Further disclosed is a double-sidedly adhering, especially carrierless, adhesive tape, and also single- or double-sidedly adhering adhesive tape comprising, on a carrier layer, the cured pressure-sensitive adhesive. Disclosed finally is the use of the pressure-sensitive adhesive or of an adhesive tape made therefrom for bonding components in electronic devices, especially in mobile electronic devices, preferably tablets, mobile phones or smart watches.

  • Publication number: 20200017723
    Abstract: A process for the continuous and solvent-free production of a pressure-sensitive adhesive based on solid EPDM rubber, the pressure-sensitive adhesive produced thereby, and an adhesive tape containing the pressure-sensitive adhesive. The pressure-sensitive adhesive is produced in a continuously operating assembly in the form of a planetary roller extruder having a filling section and a compounding section, the compounding section consisting of at least two coupled roller cylinders, by a) feeding the solid EPDM rubber and any further components into the filling section of the planetary roller extruder, b) transferring the components from the filling section into the compounding section, c) adding liquid EPDM rubber, plasticizer, tackifier resin, and any further components to the compounding section, and d) discharging the resultant pressure-sensitive adhesive, which process comprises feeding the solid EPDM rubber as a melt into the filling section.
