LNP™ ELCRIN™ CX7240BL

LNP ELCRIN CX7240BL Polycarbonate/Acrylonitrile Butadiene Styrene (PC/ABS) blend is an injection moldable, medium flow, non chlorinated/brominated flame retardant grade with incorporation of renewable PC feedstock. It has a UL94 V0@0.75mm, 5VA@3.0mm and 5VB@1.5mm flame rating and contains up to 23% renewable content. Renewable content certified by ISCC+ mass balance methodology. This grade has improved weld line strength and chemical resistance compared to standard PC/ABS blends and is a good candidate for thin wall applications. This grade also has good processability with opportunities for shorter injection molded cycle times compared to standard PC/ABS. ELCRIN CX7240BL is a product available in wide range of opaque colors and may be an excellent candidate for a variety of electronics applications such as mobile phones, tablets, audio equipment, gaming devices, thin wall industrial housings, and electric vehicle battery and energy storage equipment.
