Film laminates are formed from at least three layers A, B and C, each containing at least one plasticizer and at least one polyvinyl acetal, wherein two outer layers A and C each contain at least one identical or different polyvinyl acetal having a proportion of polyvinyl alcohol groups of 18.5 to 23% by weight, at least one inner layer B contains a polyvinyl acetal having a proportion of polyvinyl alcohol groups of 12 to 18% by weight, and at least one of the layers A, B or C contains at least one polyvinyl (iso)acetal. The film laminates can be used for the production of glass/film laminate/glass composites for motor vehicles, aircraft, ships, architectural glazings, fa&#xe7;ade components, or for the production of photovoltaic modules.

Film laminates having damping properties containing a sub-layer made of plasticizer-containing polyvinyl (iso)acetal

The invention relates to film laminates, formed from at least three layers A, B and C, each layer containing at least one plasticizer and at least one polyvinyl acetal, wherein, at least one of the layers A, B or C contains at least one polyvinyl (iso)acetal having a mean degree of polymerization of less than 3000, 10 to 25% by weight of polyvinyl alcohol groups and a proportion 50 to 80% by weight of polyvinyl (iso)acetal groups, and wherein layer B has a plasticizer content of less than 32% by weight. The film laminates can be used for the production of glass/film laminate/glass composites for motor vehicles, aircraft, ships, architectural glazings, fa&#xe7;ade components, or for the production of photovoltaic modules.
