Optical Plastic production starts with carefully selected resin, because the raw material directly affects light transmission, haze, color stability, surface quality, and processing performance. For LED lighting, display panels, architectural decoration, signage, and optical covers, the most common materials include PMMA, PC, PS, optical additives, diffusion particles, UV stabilizers, and color masterbatch.
PMMA is one of the most important materials for optical plastic sheet production. Clear acrylic can reach about 92 percent light transmission under ASTM D1003 testing, and its density is about 1.2 g/cm³ under ISO 1183 material data. This makes PMMA suitable for acrylic diffuser sheet, Light Guide Plate, Decorative Acrylic Sheet, textured acrylic panel, and high-clarity display applications.
PC is selected when the product needs stronger impact resistance and better toughness. Clear polycarbonate sheet usually provides about 88 to 90 percent light transmission, while offering much higher impact performance than acrylic in demanding applications. For industrial lighting, public lighting, protective covers, and fixtures with higher installation stress, PC diffuser sheet is often a practical choice.
Main Raw Material Typical Function Common Application
PMMA resin High clarity and good optical appearance Acrylic sheet, light guide plate, diffuser sheet
PC resin Strong toughness and impact resistance Industrial lighting cover, protective diffuser
PS resin Cost-effective diffusion performance Indoor LED diffuser sheet
Diffusion particles Scatter light and hide LED dots Panel light diffuser, ceiling light diffuser
UV stabilizer Helps reduce yellowing and aging Outdoor or semi-outdoor lighting parts
Color masterbatch Controls color and visual effect Decorative panels and customized sheets
Optical additives are also important. Diffusion particles help spread LED light more evenly, while haze adjustment controls how well the sheet hides light spots. UV stabilizers help improve long-term appearance when the material is exposed to sunlight or strong lighting conditions. Color masterbatch allows customized white, frosted, tinted, or decorative effects for project buyer requirements.
KUNXIN provides optical plastic materials including acrylic diffuser sheet, polycarbonate diffuser sheet, PS diffuser sheet, prismatic sheet, Anti-Glaring Diffuser Sheet, light guide plate, optical film, profile diffuser, and decorative acrylic sheet. The company offers PMMA, PS, and polycarbonate diffuser options, with customizable dimension and light transmission for LED lighting needs.
For bulk order production, raw material selection should match the final structure. A panel light may need balanced transmission and haze. A protective industrial fixture may need PC material. A premium architectural panel may need PMMA with stable color and surface texture. KUNXIN can support material evaluation, sample testing, thickness selection, color matching, cutting, CNC processing, thermoforming, and batch consistency control.
