7328 is sign white. It's translucent, so it reads as a solid white face in daylight but lets light through when it's lit from behind: about 30% transmission at 1/8", 22% at 3/16", and 16% at 1/4". That makes it the middle option between 7508 (opaque) and 2447 Lightbox White (more transmission, softer face), and it's what most illuminated cabinet signs, channel-letter faces, and backlit panels use when you want a bright white face with good hot-spot hiding.
This is cast material, so it laser-cuts with a clean edge, engraves crisply, and takes vinyl and UV printing well. Stocked from 1/16" through 3/4" as a full 48" × 96" sheet or precut; the 1/16" sheet comes as 48" × 72".
Also available as P95 7328, with a matte, frosted finish on one side. For sizes we don't list, or fabrication, reach out for a custom quote.

Thickness & cut tolerances
Thickness & cut tolerances
Acrylic and polycarbonate are made in metric thicknesses, so a nominal 1/8″ sheet is about 3 mm — all thicknesses shown are nominal. Cut size tolerance is ±1/8″. Need a tighter tolerance or a size we don't list? Request a quote.
Need it machined, polished, or an odd size?
We laser cut, CNC route and flame-polish in the same building. Send a quote request and a rep replies the same business day.
