Trinseo Magnum™ 545 ABS, General Purpose (discontinued **)
Categories:	Polymer; Thermoplastic; ABS Polymer; Acrylonitrile Butadiene Styrene (ABS), Molded
Material Notes:	MAGNUM® ABS resins are thermoplastic materials which provide an excellent balance of processability, impact resistance and heat resistance as imparted by the various polymer compositions. MAGNUM ABS resin are available in a wide range of melt flow rates, impact strength and heat resistance for both high and low gloss applications manufactured by injection molding, sheet or profile extrusion and thermoforming. MAGNUM ABS resins offer a wide range of processability and impact resistance for low gloss injection molding applications. Combined with heat resistance and tensile and flexural strength, MAGNUM ABS resins are used in a wide variety of injection molding applications. MAGNUM 545 ABS resin offers a balance of both easy processing and good impact strength in a low gloss resin. With a melt flow rate of 6 g/10 min. and an Izod impact strength of 290 J/m, MAGNUM 545 is an excellent general purpose ABS resin. Data provided by Dow Chemical. This product line was spun off from Dow Chemical to Styron in 2010.
