Material Notes:
Overview: MAGNUM™ 342 EZ ABS resin is a medium impact, high flow, low gloss resin often used in automotive applications. Automotive MAGNUM ABS resins offer a wide range of gloss, viscosity, impact strength and heat properties for use in numerous automotive applications. Melt flow rates from 1 to 12 g/10 min, impact strengths from 2.5 to 12 ft-lb/in and heat distortion temperatures from 165 to 190°F are available. Available primarily as a natural plus concentrates, MAGNUM ABS resins are used in a wide variety of automotive applications including structural instrument panels, consoles, pillars, and exterior trim parts requiring painting and plating.Applications:Automotive door panelsConsolesInterior trimInformation provided by Styron
