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.

Abstract: A multi-layered laminate for producing membranes for electroacoustic transducers, comprises a first layer of a polyether ether ketone film having a heat of crystallisation of at least 15 J/g, a second layer (of a thermoplastic plastic film having a heat of crystallisation of no more than 5 J/g, and an adhesive layer arranged between the first and second layers. Alternatively, the first and second layers are defined by their shrinkage properties after 15 minutes at 200° C.: the first layer has shrinkage of more than 10% in at least one direction, and the second layer has shrinkage of less than 10% in the longitudinal and transverse directions. A laminate constructed in this manner exhibits lower fold formation when processed using multi-cavity thermoforming. The laminates are useful for the production of membranes for electroacoustic transducers.
