FILM MULTILAYER MATERIAL WITH PROPERTIES OF NOISE KILLING, CONTAINING ELEMENTARY LAYER OF THE POLYVINYL(ISO)ACETAL FROM PLASTICIZER Russian patent published in 2016 - IPC G10K11/168 B32B17/10 B32B27/08 C08L29/14 

FIELD: machine building.

SUBSTANCE: invention is related to a suitable, for example, as an intermediate layer in multilayer safe glass film multilayer material which can be used for producing glass system/film multilayer material/glass for vehicles, aircraft, ships, building glazing, structural elements faces or for producing photovoltaic modules. Versions of film multilayer material are formed with at least three layers A, B and C, containing at least one plasticizer and, at least, one polyvinylacetal, with that, both outer layers (A) and (C) contain at least one identical or different polyvinylacetal, or, at least, one inner layer (B) contains at least one polyvinylacetal, or at least one layer A, B or C contains at least one polyvinyl(iso)acetal.

EFFECT: technical result is producing film multilayer material, which has good noise suppression properties, as well as good permeable properties.
