  • Laminated glass comprising interlayer film layers with a pigmented frame
    Patent number: 11396160
    Abstract: Laminated glass having an opaque frame area is obtained by laminating at least one film A containing polyvinyl acetal PA and optionally at least one plasticiser WA and at least one film B containing a polyvinyl acetal PB and at least one plasticiser WB between two glass sheets, wherein prior to lamination the amount of plasticiser WA in film A is less than 22% by weight the amount of plasticiser WB in film B is at least 22% by weight and film A comprises at least on one surface a non-transparent region.

  • THIN FILMS COMPRISING PLASTICIZER-FREE POLYVINYL-CO-ACETAL
    Publication number: 20190263984
    Abstract: Polyvinyl-co-acetal films having a thickness of 1 ?m to 1000 ?m and containing less than 10 wt. % plasticizer are suitable for use as a hot melt in molding operations, exhibiting shorter cycle times as compared to conventional polyvinyl acetals. The polyvinyl-co-acetals are obtained by reacting at least one polyvinyl alcohol with at least two different aliphatic keto compounds, each containing 2 to 10 carbon atoms.
