An interlayer for laminated glasses, includes two outer layers of a material selected from poly(vinyl butydownral) (PVB) and poly(ethylene-vinyl acetate) (EVA), assembled by an adhesive nanocomposite layer including a first, discontinuous phase consisting of polymeric nanodomains having a glass transition temperature (Tg) of between −50° C. and −30° C., and a second, continuous polymeric phase, referred to as the matrix, having a glass transition temperature (Tg) lower than that of the first phase, the first phase being dispersed in the second phase.

Hybrid acoustic interlayer consisting of an adhesive core layer made of polymer-matrix nanocomposites

A viscoelastic plastic interlayer intended to be arranged between two glass sheets of a glazing in order to provide it with vibroacoustic damping properties, includes two outer layers of thermoplastic adhesive, an inner layer arranged between the two outer layers, the inner layer having a loss factor tan &#x3b4; greater than or equal to 1.6 at 20&#xb0; C. and for a frequency range of between 2 kHz and 8 kHz, and first and second barrier layers arranged respectively between the outer layers and the inner layer, and composed of a viscoelastic plastic material.

Hybrid polymer for visco-elastic plastic spacer

A method for re-establishing or tending to re-establish symmetrical distribution of temperatures between right-hand and left-hand sides of a cross section of a flow of molten glass that has been routed in a feeder including at least one bend area, thermal asymmetry having been induced by flowing round a bend. The feeder includes a flow channel, formed from refractory and insulative material elements and including a horizontal sole plate and two lateral walls, and a vault capping the channel, formed of a refractory roof and lateral parts including burners. In an area of each bend, the flow channel is modified by choosing a corresponding inclined sole plate portion, the inclination being chosen so that the flow channel is deeper in an outside region of the bend than in its inside region, heights of the two lateral walls of the channel being modified accordingly.
