INTERLAYER FOR LAMINATED GLASS, AND LAMINATED GLASS

摘要

An interlayer for laminated glass is provided which is capable of improving the flexural rigidity of laminated glass, is capable of improving the sound insulation properties of laminated glass, and is capable of inhibiting the formation and growth of bubbles in laminated glass. An interlayer for laminated glass according to the present invention is provided with a structure having one layer or a structure having two or more layers, and is provided with a first layer which includes a polyvinyl acetal resin and a plasticizer. The glass transition temperature of the first layer is not more than 10˚C. The elastic modulus of the first layer at 30˚C is at least 285000 Pa.
