ClearCast Optima 100

UV-stabilized cast acrylic is commonly chosen for outdoor sign faces because it resists weathering and yellowing better than many basic plastics. Service life still depends on sheet thickness, exposure, mounting stress, and the specific manufacturer's warranty.

Optically clear cast acrylic can transmit light effectively, but a truly edge-lit sign normally needs a grade engineered to scatter light from its edges. Confirm the sheet's light-transmission and light-guiding specifications before pairing it with LED strips.

Use a plastic-compatible drill bit, low speed, light pressure, and adequate support beneath the sheet. Holes should allow clearance for thermal expansion because tightly fastened acrylic can crack around the mounting points.

No, cast acrylic generally offers better optical clarity and scratch resistance but lower impact resistance than polycarbonate. Polycarbonate is the safer choice for vandal-prone signs, while acrylic is often preferred when appearance and UV stability dominate.
