Features & Benefits
Optimized for Small, Detailed Parts
With a melt flow rate (MFR) of 17.5, LEXAN 223S flows easily into tight molds, making it ideal for intricate components like electronic housings, connectors, and precision gears. This reduces scrap and ensures dimensional accuracy.
Built-In Flame Retardance
LEXAN™ PC 223S is UL94 V-0 rated at 1.5 mm, helping manufacturers meet stringent fire safety standards. This is especially critical in consumer electronics, lighting, and automotive interiors where fire resistance is non-negotiable.
UV Stabilized for Outdoor Use
Designed to resist yellowing and degradation, LEXAN 223S performs reliably in outdoor or high-UV environments. It’s a smart choice for lighting enclosures, electrical boxes, or any component exposed to sunlight over time.
