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.

Abstract: A reactive pressure-sensitive adhesive element that includes: i) a carrier layer; ii) a first adhesive layer arranged on a first surface of the carrier layer that comprises a first UV-curable pressure-sensitive adhesive; and iii) a second adhesive layer arranged on a second surface of the carrier layer facing away from the first surface, wherein the second adhesive layer comprises a second UV-curable pressure-sensitive adhesive. Each of the first and second UV-curable pressure-sensitive adhesives, based on a mass of the respective pressure-sensitive adhesive, comprises: x) one or more poly (meth) acrylate compounds in a combined mass fraction from 35% to 85%; y) one or more polymerizable epoxy compounds in a combined mass fraction from 10% to 50%; and z) one or more photoinitiators in a combined mass fraction from 0.1% to 5%. Further, the carrier layer comprises a foam carrier, the foam carrier comprising one or more polyolefins.
