That's good to know, I just found a truview acrylic sheet with UV absobtion for paintings online, hopefully it has some UVA blocking ability, will be contacting the company soon.
Thanks for the help, everyone. Looks like I got my work cut out for me if I'm gonna be able to block UVA while keeping visible transparency, the UV filters seem like a great choice but price and patent issues might be a problem.
Ok, thanks, cause I need the most transparent plastic I can get with this, I know most plastics are somewhat opaque atleast to shorwave UV normally but I need something that will be opaque to longwave UV like you would have from blacklights, is Ciba still in business?
Thanks, Chris, Pat. How expensive is transparent ABS compared to say transparent cast acrylic? Is the clarity the same? Can a UV absorber be added to acrylic? What are some common UV absorbers in use?
Hi, I am new to the forums, I am working on a project that would require a plastic similar to lexan or plexiglass that's transparent at visible wavelengths but opaque or nearly opaque at longwave UV wavelengths. Is there such a plastic on the market?
