SABIC LEXAN™ Copolymer EXL8414 Polycarbonate (PC) (Americas)
Categories:	Polymer; Thermoplastic; Polycarbonate (PC)
Material Notes:	LEXAN EXL8414 is a PC/siloxane copolymer resin with medium flow, excellent low temperature impact and up to 25% post consumer recycle content. Availability of resin is restricted and lead times are longer due to limited manufacturing capability. Higher color variability and contamination risks including black specs needs to be considered before approval for use in applications. Contact your technical sales representative with questions. Features: High Impact Resistance Information provided by SABIC
