Cast Acrylic is transparent, moisture resistant and half the weight of glass but 17 times stronger. Cast acrylic has a higher molecular weight than extruded acrylic, making it a better choice for shaping, machining and laser cutting. Common uses for Cast Acrylic are signage, aquariums, POP displays and furniture. Acme Plastics' Paper Masked Acrylic Cast Color Sheets come in a rainbow of colors and available in several thicknesses. Standard sheet sizes are 24" x 48", 48" x 48" and 48" x 96". Acme Plastics has Sample Black Cast Acrylic Sheets.
