LNP™ ELCRES™ EXL9334U

Chemical Family: Polycarbonate (PC)Siloxanes

LNP™ ELCRES™ EXL9334U is based on polycarbonate (pc) siloxane copolymer resin, featuring excellent UV resistance. It is UL94 V0 rated at 1.5mm for flame retardancy using non-bromine, non-chlorine FR systems. This medium-flow, opaque material is suitable for injection molding and sheet extrusion applications. It offers extreme low-temperature ductility at -40°C and excellent processability, with opportunities for shorter injection molding cycle times compared to standard PC. Available in a wide range of opaque colors, it is targeted for a variety of applications.

Note: ¹ The information stated on Technical Datasheets should be used as indicative only for material selection purposes and not be utilized as specification or used for part or tool design. ² UL Ratings shown on the technical datasheet might not cover the full range of thicknesses and colors. For details, please see the UL Yellow Card. ³ Measurements made from laboratory test coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article. ⁴ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.
