polycarbonate edges or sidewall material (lexan)

[voodoo]

Does anyone know much about polycarbonate?


Lightningboards.com

uses them for their edges.
I think this is what they make out glass eyes out of.

this is the discription:


POLYCARBONATE

The most common type of polycarbonate plastic is one made from Bisphenol A, in which groups from Bisphenol A are linked together by carbonate groups in a polymer chain. This polycarbonate is a very durable material, and can be laminated to make bullet-proof "glass", though “bullet-resistant” would be more accurate. The characteristics of polycarbonate are quite like those of polymethyl methacrylate (PMMA; acrylic), but polycarbonate is stronger and more expensive. This polymer is highly transparent to visible light and has better light transmission characteristics than many kinds of glass. CR-39 is a specific polycarbonate material with good optical and mechanical properties, frequently used for safety eyeglass lenses.

Polycarbonate has :

a density of 1.20 g/cm3
a use range from -100°C to +135°C
a melting point around 250°C
a refractive index equal to 1.585 ± 0.001
a light transmission index equal to 90% ± 1%
poor weathering in an ultraviolet (UV) light environment
Polycarbonate is becoming more common in housewares as well as laboratories and in industry. It is often used to create protective features, for example in banks as well as vandal-proof windows and lighting lenses for many buildings. Other products made from polycarbonate include safety eyeglass lenses, and automotive headlamp lenses.
