How do I tell the difference between Acrylic and Polycarbonate, and which do I need?

Top choices between clear or near clear plastics, acrylic plexiglass sheet and polycarbonate panel are often considered as solutions for a broad range of optical applications. How do they compare? The answer depends...

Both Acrylic and Polycarbonate are half the weight of comparably sized glass by volume. For what you lose in weight, you gain in strength with either product. Both are synthetic glass, and each offers tremendous flexibility.

Acrylic has roughly 17 times the impact resistance. Polycarbonate is the stronger material at 250 times the impact resistance of standard glass.
