DETALHES DO PRODUTO

LED Light Acrylic Sheet

LED Light Acrylic Sheet is a functional optical panel specifically designed for LED light sources. By adding nano-scale light diffusion particles to the PMMA substrate, it achieves a balance of high light transmittance (85-92%) and high haze (90-98%). It offers three major series: diffusion plates, light guide plates, and uniform light plates, with thickness ranging from 1.5mm to 10mm and standard size of 1220×2440mm. Custom dot pattern designs are available, making it the core material for LED panel lights, light boxes, and decorative lighting.
