Resin film for laminated glass, and laminated glass and preparation thereof
Abstract:
Embodiments relate to a resin film for laminated glass, laminated glass comprising the resin film, and a process for manufacturing the laminated glass. The resin film for laminated glass comprises a resin layer comprising a polyvinyl acetal resin and a contact surface in direct contact with glass, wherein the contact surface has an Rz roughness of 25 to 90 μm and a maximum static friction coefficient at 20° C. of 0.85 to 1.60, and the compressive elastic deformation index measured in the perpendicular direction from the contact surface at 35° C. is 40 to 310 μm/N.
