Description
[Plexiglas] A registered trademark for a type of UV filtering acrylic sheeting produced by Arkema. Plexiglas® G UF-3 is slightly tinted and blocks about 97% of the UV light, but produces a slightly yellowish cast. Transmission starting at 395nm. It may have a static charge.
Synonyms and Related Terms
Plexiglas® G [Arkema]; UF-3 Plexiglas; Plexiglas® UF-4 [Arkema]; Polymethylmethacrylate (PMMA); Acrylite® OP2; UV filtering acrylic sheeting
Applications
Plexiglas® is used for a variety of exhibit related applications. Plexiglas® G UF-3 is used for glazing, framing, and possibly vitrines.
Personal Risks
Grinding, sanding, and/or sawing can cause dust which may result in respiratory hazard. Also, the product may release fumes and/or vapor of variable composition, depending on processing time and temperature.
Arkema: SDS

Plexiglas G (no UV filtering) tested in 2019.
Working Properties
A variety of saws can be used to cut Plexiglas®: circular, band, scroll, saber, hole, and veneer saws. Routers can also be used on Plexiglas®. Plexiglas® can also be turned on a lathe to give a semi-matte surface. When drilling, best results are obtained when using a modified standard twist drill. Specially ground drills for Plexiglas® acrylic sheet are available.
After cutting Plexiglas® acrylic sheeting it is often desirable to scrape the edges to remove nicks or burrs and improve the appearance.[1]
Plexiglas® can be joined using methylene chloride (solvent-dissolving acrylic), acetoxy cure silicone sealants, or an epoxy; these joints are strong enough for loadbearing for medium to heavy weights, but bending acrylic sheeting is stronger. Plexiglas® acrylic sheeting is a thermoplastic and can be shaped once pre-heated between 325°F and 350°F, but the sheets can be cold formed as well by springing the material into a curved channel support.[2]
Forms and Sizes
Sheet sizes: 48x96", 60x90", 72x96"
Thicknesses: 0.118, 0.177, 0.236, 0.354, and 0.472”
