高刚性PC 基础创新塑料(美国) EXL4419-739 中流动 玻纤增强材料
LEXAN™ EXL4419 resin
Polycarbonate
SABIC Innovative Plastics
9.0% 玻璃纤维增强材料
产品说明：
LEXAN EXL4419 polycarbonate (PC) siloxane copolymer resin is a 9% Glass Fiber (GF) reinforced opaque injection molding (IM) grade. This medium flow resin offers much higher ductility, improved release characteristics and excellent processability with opportunities for shorter IM cycle times when compared to GF reinforced standard PC resins. LEXAN EXL4419 resin is available in opaque colors only and is an excellent candidate for a broad range of applications that require a combination of stiffness and ductility.
