Richardson, Texas, is introducing its Polyvision glass, which it
expects to be available at the end of March. Polyvision glass, also
known as privacy glass or electrically switchable glass, is based
on a patented technology called Polymer Dispersed Liquid Crystal
by Kent State University.
Polyvision glass is designed to turn from milky white to transparent
or vice versa at the flip of a switch. The company says it is ideal
for interior applications such as conference rooms, executive offices,
homes, bank teller windows, dividers in hospital intensive care
areas and more.
According to the company, compared to existing products, Polyvision
has 5-percent better transmission, reduced haze, wider viewing angles
and looks more like regular glass when the power is on, yet still
maintains image blocking power when the power is off.
