Made of cast acrylic, black/white plexiglass is weather resistant, easily fabricated, lightweight, and has a high impact resistance. Our LED lor changing, backlit black and white acrylic sheeting uses a special formula to appear dark during the day, with a bright, white light at night. Black/white plexiglass sheeting is ideal for sign applications when you want your display or advertisement to remain hidden in the light, showing when the lighting is deployed.
