light diffusing PC, light diffusion PC granules for LED lamp cover, anti-glare polycarbonate, high transmittance light diffuser PC, commercial LED lighting raw material

The commercial and architectural LED lighting market keeps upgrading toward low-glare and uniform illumination. Light diffusing polycarbonate (PC) is replacing traditional acrylic and PS diffuser materials and becomes the preferred optical raw material for lighting manufacturers worldwide. Light diffusing PC blends PC resin with nano light diffusing agents to convert sharp LED point sources into soft surface light, eliminating hotspot and reducing UGR glare. It delivers 82–88% light transmittance with haze up to 99%. It retains polycarbonate’s inherent advantages: high impact strength, good heat resistance and anti-yellowing performance, resisting deformation under continuous heat load. It suits injection molding & extrusion for LED panel lights, downlights, linear lights and office grille lamps. We supply general grade, UV-stabilized outdoor grade and UL94 V0 flame retardant light diffusing PC granules. Haze, base color and melt flow rate can be customized to help lamp factories improve production yield and shorten mold trial time. With rising commercial lighting projects in Southeast Asia and the Middle East, export demand for optical PC resin keeps growing steadily.
