ASYMMETRICAL GLASS LAMINATES HAVING COMPOSITE INTERLAYER AND RELATED METHODS
Various embodiments for a laminate glass article and related methods are provided. The laminated glass article includes a first and second glass layers with an interlayer positioned therebetween, comprising: a polymer core layer comprising a high modulus polymer (e.g. polyethylene terephthalate, polycarbonate, polyacrylate, and polyimide); a first low modulus material layer (e.g. first TPU or first PVB or first EVA) configured between the first layer and the polymer core layer; and a second low modulus material layer (e.g. second TPU or second PVB or second EVA) configured between the second layer and the polymer core layer.
INTERLAYER FILM FOR LAMINATED GLASS
Provided is an interlayer film for laminated glass which is excellent in sound insulation property and has improved sound insulation performance not only in a coincidence region but also in a mass-dominated region.
The interlayer film for laminated glass includes a sound insulating layer which is formed from a composition (A) containing at least one resin (a1) selected from a thermoplastic resin and a thermosetting resin, wherein a tan obtained when a dynamic viscoelasticity of a sheet, which is obtained by molding the composition (A) to have a thickness of 0.8 mm, is measured at a frequency of 0.3 Hz in a tension mode has a maximal value at a temperature T.sub.A ( C.), T.sub.A ( C.) is in a range of 50 to 50 C., and the tan at T.sub.A ( C.) is 2.5 or more.
Modular wall panels and planar structures
A modular glass panel comprising a glass structure having at least one thin glass sheet having a thickness ranging from about 0.5 mm to about 2.0 mm, a backing frame positioned adjacent the glass structure and situated along the perimeter of the glass structure, and a polymer layer intermediate the glass structure and backing frame to adhere the glass structure together with the backing frame. The glass structure can further comprise the at least one thin glass sheet and a second glass sheet having a polymer interlayer therebetween. The backing frame generally has a geometric cross-section with a rounded interior edge adjacent the glass structure to prevent breakage of the structure upon loading or impact of an exterior surface of the structure.
HEATING FILM AND METHOD FOR MANUFACTURING SAME
The heating film including: a transparent substrate; a coating layer provided on the transparent substrate and having a refractive index of 1.450 to 1.485; and a metal foil pattern provided on the coating layer, in which a ten-point average roughness (Rz) of a surface of the metal foil pattern is more than 0.9 m.
GLASS LAMINATE WITH INLAY OBSCURATION HAVING SUPERIOR STRENGTH AND OPTICAL QUALITY
The use of camera-based safety systems is growing at a rapid rate in modern automobiles. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. However, the optical quality of the windshield is less than optimal. One of the problems is caused by the typical black enamel frit that is printed on the glass, prior to heating and bending, to hide or obscure the camera hardware. The abrupt thermal gradients during bending, caused by the heat absorbing black frit, result in a high level of distortion in the camera field of view. The object of this invention is to provide laminated automotive glazing having an obscuration area produced by creating an obscuration after heating and bending the glass by removing a portion of the plastic interlayer glass in or near the camera field of view (camera obscuration) or/and in the edges of the windshield (black band) and replacing it with an inlay made of a substantially opaque plastic or other suitable material in or near the camera field of view (camera obscuration) or/and in the edges of the windshield (black band) rather than printing and firing an enamel frit on the glass. This results in a laminate having superior optical quality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration.
IMPROVED ALIGNING AND LAMINATING METHOD FOR THE PRODUCTION OF THIN LAMINATED GLASS FROM GLASS PANES WHICH DO NOT FIT TOGETHER ACCURATELY
A method for producing laminated glass or a precursor thereof using a first glass pane with a thickness of at least 1.4 mm and a second glass pane with a thickness of not more than 1.0 mm, the first and second glass panes differing in curvature and/or locally in shape, includes aligning an arrangement including the first and second glass panes and a laminating film by positioning a side edge of the arrangement against a stop element; pre-fixing the aligned arrangement at at least two locations on the positioned side edge of the arrangement by one or more fixing elements and heating, after which the fixing element or elements are removed again; and forming a fixed arrangement by passing the pre-fixed arrangement through a roller arrangement with the pre-fixed side edge of the arrangement ahead. The arrangement is heated in sections during passage.
INTERLAYER FILM FOR LAMINATED GLASS, AND LAMINATED GLASS
There is provided an interlayer film for laminated glass with which the occurrence of a poor appearance due to white cloudiness in laminated glass can be suppressed even though the interlayer film is provided with a layer containing silver.
