CX7240U-XH
Forever
CX7240U-XH is an injectable grade of Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) blend that is UV stabilized and flame retardant. It offers a medium flow rate and does not contain chlorine or bromine. With a UL94 V0@.75mm flame rating, as well as 5VA@3.0mm and 5VB@1.5mm flame ratings, it meets high safety standards. This grade also exhibits improved chemical resistance compared to standard PC/ABS blends, making it suitable for thin wall applications.
