Abstract: A latent-reactive hot-melt adhesive composition comprising a) at least one first thermoplastic polymer, which is monofunctionally reactive to NCO groups and has a high tensile strength, b) at least one second NCO-reactive polymer and/or oligomer, polymer miscible with the first polymer a), which is at least di-functionally, preferably tri- or multifunctionally, reactive to NCO groups and has a melting temperature (Tm), which is lower than the melting temperature (Tm) of polymer a), and is in liquid form, c) at least one solid, surface deactivated di- and/or polyisocyanate, d) optionally one or more further thermoplastic polymer(s) which does not or do not react to NCO groups. Such compositions have significantly improved mechanical characteristics.

Abstract: An airbag is made by producing a laminated material including a backing layer, a first polymer layer facing the backing layer, and a second polymer layer facing away from the backing layer. The first polymer layer has a glass transition temperature of 10° C. or less. The second polymer layer has a storage modulus at least 1 MPa at 90° C.

Abstract: The invention relates to an airbag with wall parts (1, 2), which comprise or consist of a laminated material, the laminated material comprising: (a) a backing layer (3), in particular comprising a gas-permeable textile sheet-like structure, preferably a layer of woven or knitted fabric, and (b) an at least two-layered, in particular co-extruded polymer film (4), a first polymer layer (5), facing towards the backing layer, having a glass transition temperature Tg1 of less or equal than 10° C., with preference less or equal than 0° C., with particular preference less or equal than ?20° C., and a second polymer layer (6), facing away from the backing layer, having a storage modulus according to the torsion pendulum test as specified by DIN 53 445 of more or equal than 1 MPa at more or equal than 90° C., with preference more or equal than 110° C. and with particular preference more or equal than 120° C.
