I'm redoing a sign for a customer. It's a 2*8 box frame with a white plastic part that slips in. What material is this? I'm not sure, I think it's plexiglass.

Plexiglas is a brand name - it could be any type of white acrylic or polycarbonate. Kinda hard to tell from here.

Thanks a lot Bob. That should be all I need.

Mike,
When you are removing the original piece, make sure it is a little undersize for expansion clearance. If it is the original face in the sign, it probably is cut properly for that. If so, cut your new face the same size. If the original is something like 23-3/4" x 95-1/2", cut the new face the same size, not 24" x 96". Otherwise, there will be heat associated expansion problems.

Also ask your supplier for sign-white, it is often an available option that looks better in backlit use.

Mike,
To determine what it is, knock on it with your knuckle. If it sounds like a thud (or "softer" ) plastic it may be plexi type material. If it sounds like a higher (harder) type of feel then it's probably lexan or that type. The plexi is cheap and the lexan type is higher. There are other materials than are stronger than lexan even. If you're replacing one and it's in a vandal type location then the lexan or better is more appropriate for that, other then that you can use the plexi type.
