SABIC LEXAN™ Copolymer EXL4019 Polycarbonate (PC) (Europe)
Categories: Polymer; Thermoplastic; Polycarbonate (PC)
Material Notes: LEXAN EXL4019 is an opaque 9% Glass Fiber (GF) reinforced polycarbonate (PC) siloxane copolymer resin for injection molding (IM) applications requiring improved stiffness. This resin also offers improved ductility over conventional GF reinforced PC resins in combination with medium flow characteristics and excellent processability with opportunities for shorter IM cycle times when compared to standard PC. LEXAN EXL4019 resin is a product that may be an excellent candidate for a wide variety of applications. Available in limited colors only.

Features: High Impact Resistance
