The world can be a dangerous place. That’s why so many glazing and security professionals make the safe choice with Plexiglas® SB acrylic sheet bullet-resistant glazing material. Its patented protection serves every day in high security environments – wherever weapons, violence, or vandalism are a risk. Plexiglas® SB acrylic sheet offers a lightweight, crystal clear, non-laminating alternative for your protective barrier designs and it’s half the weight of bullet resistant glass of the same UL class rating. When clarity and security are important, no material outshines it. Plexiglas® SB acrylic sheet meets UL 752 Level I and II requirements for use in bullet resistant applications involving small firearms. It is also available with an abrasion resistant coating. Plexiglas® SBAR acrylic sheet offers 40 times the abrasion resistance of un-coated acrylic.
