SABIC CYCOLOY™ FR Resin CX7720 Polycarbonate + ABS (PC+ABS)
Categories:	Polymer; Thermoplastic; ABS Polymer; Polycarbonate/ABS Alloy, Unreinforced
Material Notes:	CYCOLOY CX7720 Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) blend is an injection moldable, high flow, high heat resistant, non chlorinated/brominated flame retardant grade. It has a UL94 V0@1.2mm, 5VA@2.5mm and 5VB@1.5mm flame rating. This grade has improved chemical resistance compared to standard PC/ABS blends and is a good candidate for thin wall applications. Features: Hydrolytic Stability,Chemical Resistance,Flame Retardant,Thin Wall,Heat Stabilized,Good Mold Release Information provided by SABIC
