Cast Acrylic Sheets: Premium Clarity, Unmatched Durability & Design Versatility
What are Cast Acrylic Sheets?
Cast acrylic sheets are engineered through a meticulous cell-casting process, where liquid methyl methacrylate (MMA) is poured between polished glass molds and thermally cured. This advanced manufacturing technique creates acrylic sheets with superior optical properties, exceptional surface quality, and enhanced chemical resistance compared to extruded alternatives. Ideal for precision applications demanding premium performance.
Why Choose Cast Acrylic Over Extruded?
Key Advantages:
Optical Excellence
≥92% light transmission (near-crystal clarity)
Low haze (<0.5%) & brilliant surface gloss
Minimal optical distortion for critical visual applications
Superior Machinability
Excellent thermoforming performance (maintains uniform thickness when bent)
Laser cuts cleanly without yellowing or burrs
Superior polishability for flawless edge finishes
Enhanced Durability
Higher molecular weight = improved chemical/solvent resistance
Withstands prolonged UV exposure (optional UV-stabilized grades)
Outstanding weatherability for indoor/outdoor use
Material Integrity
Consistent thickness tolerance (±5%)
Homogeneous composition without internal stresses
Reduced risk of stress-cracking during fabrication
