Mechanical properties of ABS/polycarbonate blends

Abstract

The mechanical properties of extruder compounded blends of ABS and polycarbonate in the form of extruded-sheet and injection-molded bars are reported and compared with commercial products based on these components. The modulus and tensile yield strength exhibit a nearly additive response to blend composition while percent elongation at break shows a minimum vs. composition. Notched Izod impact strength is nearly constant at the level of pure ABS up to 50% polycarbonate and increases rapidly upon further addition of polycarbonate.
