A process is for manufacturing a complex motor vehicle glazing including a glass pane, an elastomer seal and a metal insert overmolded by the elastomer seal. The process includes inserting an edge of a glass pane and a metal insert into an encapsulation mold forming a leaktight cavity around the edge of the glass pane, filling the leaktight cavity containing the edge of the glass pane and the metal insert, by injecting an encapsulation composition including a polypropylene (PP)/thermoplastic elastomer (TPE) compound in the molten state, cooling the encapsulation composition to form an elastomer seal in which the metal insert is integrated, and releasing the elastomer seal from the mold. The PP/TPE compound includes from 30% to 80% by weight of polypropylene (PP) and the metal insert is covered over its entire surface liable to come into contact with the encapsulation composition, with a polypropylene coating.

Encapsulation method

An illuminating glazing unit includes a first sheet having a first main face, a second main face and an edge face; a second sheet having a first main face, a second main face and an edge face; a lamination interlayer having an extent smaller than that of each of the glass sheets and defining a space between the edge of the second main face of the first sheet and the edge of the first main face of the second sheet; a strip of LEDs, including a printed circuit board and a plurality of LEDs, positioned so that the emitting faces of the LEDs face the edge face of the first sheet; and an encapsulating element made of an opaque polymer encapsulating at least the edge face of the second sheet and the LED strip. The PCB bears against the first main face of the second glass sheet with a plurality of spacers and the space is filled by the opaque polymer.

Illuminating glazing panel

This layered element () for encapsulating an element () that is sensitive to air and/or moisture, especially an element that collects or emits radiation such as a photovoltaic cell or an organic light-emitting diode, comprises a polymer layer () and a barrier layer () against at least one face (A) of the polymer layer. The barrier layer () has a moisture vapor transfer rate of less than 10g/mper day and consists of a multilayer of at least two thin hydrogenated silicon nitride layers () having alternately lower and higher densities.

Layered element for encapsulating a senstive element

A luminous glazing unit including at least one substrate formed by a transparent glazing element; at least one light source; and at least one light extraction device for extracting the light, the extraction device being arranged to create a luminous region, the extraction device being formed by at least one fibrous layer.
