Clear Acrylic Sheet is a highly transparent sheet made from 100% optical-grade PMMA (Polymethyl Methacrylate) through casting or extrusion processes. It offers 92% light transmittance, comparable to optical glass, yet provides 17 times the impact strength and 50% weight advantage of glass. The surface undergoes precision polishing with Ra value ≤0.02μm, achieving a mirror-like finish. Standard size is 1220×2440mm with thickness ranging from 1mm-50mm, supporting custom cutting, making it an ideal glass replacement material.
