Re: Mac 22 Windows
not sure why someone would use lexan/polycarbonate instead of plexiglas/acrylic for anything on a boat...
the lexan scratches easier, it discolors over time (is NOT as UV stabile) and it cant be re-polished to like new condition when it starts to degrade... but it will take a severe, acute impact.... but its more expensive.
Plexiglas and Lexan are both brand names and are about twice the price of buying the product as acrylic and polycarbonate with another brand name attached....
the plexiglas will re-polish to like new if it scratches, but its way more resistant to scratching to start with. (better clarity), it does not discolor over time (more UV stabile than polycarbonate/lexan), its a lot cheaper and it's about 20 times stronger than glass.
compact discs are made out of lexan, that's why they scratch so easy...
helicopter globes and windows are made out of plexiglas, as are the windows in submarines....
but I suppose if your looking for bullet proof, then lexan would be the better choice. plexiglas will withstand sharp impacts about 20 times better than glass, and it will stand up to the same shear pressures as lexan, OTHER THAN, a sharp acute impact like a hammer or a bullet... plexi is stronger than glass but lexan will shed bullets better, but only in the thicker windows. for the normal wind and wave action we may ever encounter on our boats, acrylic/plexiglas is a better option.
