Forgive me if this is posted somewhere else. What are the differences between plexiglass and lexan? I know Lexan is a type of (or name brand) style of plexiglass, but I'm pretty sure it has different properties too. I can get genuine lexan at work and this would save me a few bucks from buying a piece of tempered glass, plus I can cut it myself.

Also, I've heard rumors that either plexiglass or lexan lets of toxic fumes (I think formaldehyde) when cut (the friction causes heat) and when the sheet is heated/burnt. Anyone know if there is truth behind this?

People use Lexan XL10. You can get it at Home Depot and Lowes. It is used becuase it blocks UV. Haven't heard of anyone using plexiglass.

XL10 is special because it blocks UV, but this is a coating on the material as opposed to the material itslef.

Lexan is polycarbonate. Plexiglass is acrylic. There are slightly different properties to them.

Lexan is made to handle more heat (600 degrees), plexiglass will melt.
