AUTOCLAVE LAMINATION

.

PROCESS

This is the process in which the union between the glass and the polycarbonate material that make up the stratified takes place. In Viraver lamination is carried out in an autoclave, which consists in subjecting the laminate to the simultaneous action of pressure, temperature and vacuum in order to generate the intimate union of the materials. Viraver is equipped with a new large autoclave for polycarbonate last equal to 29.53ftx10.83ft (9mx3,30m).

TECHNOLOGIES

INFRARED FILTER

Viraver has the means to research, based on functionality and needs, shielding glass against infrared radiation, to reduce the effect of sun radiation up to 55%. In order to achieve this, Viraver uses shielding solutions through the use of special interlayers or selective films incorporated within the plastic interlayer.

HEATING CIRCUITS

Flat and curved glass with heating elements can be produced with demisting and de-icing functions which guarantee maximum visibility in all temperature and humidity conditions.

The heating effect is obtained by using micro-wire technology.

ANTI-SCRATCH COATING

The fundamental feature of plastics is their ductility and lightness. Unfortunately, they tend to deteriorate in the course of day to day use.

Signs of this deterioration include scratches, opacity and yellowing.

To increase the durability of polycarbonate products, Viraver has developed a special anti-scratch coating which hardens the surface and makes it much more resistant than the original product.  The end product acquires the required hardness imposed by international norms (ECE R43 e DOT).
