Double Elephant PMMA SX-306 Optical Grade Virgin Pellets
Product Overview：
SX-306 is an optical-grade virgin PMMA (polymethyl methacrylate / acrylic) resin produced by Suzhou Double Elephant Optical Materials Co., Ltd. — China’s leading PMMA manufacturer with 300,000 MT annual capacity. This low-MFR extrusion grade features 93% light transmittance, ultra-low haze (0.3%), and high melt strength, specifically designed for extruded light guide plates, diffuser sheets, and thick-wall optical panels. LEMA supplies genuine Double Elephant SX-306 with original 25kg packaging and full TDS/COA.
Key Features：
93% light transmittance — glass-like optical clarity, haze only 0.3% Low MFR 1.6 g/10min — high melt strength, ideal for extrusion of wide/thick panels without sag or sink marks Excellent surface hardness — Rockwell M98, scratch-resistant for signage and panels Good weatherability — resistant to UV aging and yellowing for outdoor use Virgin, unfilled, natural water-white — no recycled content, no additives
