PVB shaping or stretching

for windscreen production

Used for:

PVB Shaping or stretching prepares PVB interlayer sheets for the production of windscreens.

It gives both commercial and economic benefits to the windscreen producer:

• increases the aesthetic and comfort values of top-shaded windscreens.
• gives savings of 15-25 % with top-shaded PVB and 10 % with uniformly coloured PVB and wedge PVB.
