MECHANICAL AND FLAMMABILITY RESISTANCE PROPERTIES OF EXTRUSION ENHANCED ABS/PC NANOCOMPOSITES

摘要

ABS and polycarbonate are renowned for their low temperature properties whereas their blends have enhanced flammability resistance and lower cost properties. The use of nanoparticles in combination with polymeric materials to create plastic nanocomposites (PNCs) is a current trend. The infusion of these nanoparticles in polymeric matrix is typically carried out via sonication. In this project, we explore the alternative but very viable process of extrusion as a nanoparticle infusion process, and present the results obtained for the mechanical and flammability resistance properties of nanoclay-infused ABS/PC blends. Torque Rheometry data indicate that processability is enhanced with small amounts of nanoclay up to the 4.0 PHR level. Optimal mechanical properties are attained at the 3.0 PHR nanoclay level whereas flammability resistance properties increase with increase in nanoclay level.
