Dongguan Forever Co.,Ltd is the manufacture of the China origin cheap UV stablized PC polycarbonate Granules Polymer Resin
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 [email protected] flame rating, as well as [email protected] and [email protected] 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.
