Acrylic = Plexiglass = Perspex, they're all basically the same thing, give or take slightly by manufacturer. They're all acrylic, generically. Some may have different coatings or surface texture (scratch reduction, anti-glare, UV reduction, mirroring, etc.). They all will get a slight static charge. Just simply peeling off the protective paper will generate a HUGE static load that you can even hear building up.
A lot of the good acrylic cleaning solutions will reduce static charge. I usually mist some water on the paper while laser cutting, so having that moisture helps as well to reduce static.
True... just saying "static" isn't much help here.
