Title: Ageing of PC/PBT blend: Mechanical properties and recycling possibility
Author: Sanchez, EMS
Abstract: A polycarbonate (PC) and poly (butylene terephthalate) (PBT) blend is extensively used for moulded automobile parts. is tough and stable to 300 degrees C and PBT has relatively good solvent resistance. An alloy formed with those two polymers a material with good chemical resistance as well as good heat and impact resistance. In this work, a PC/PBT with and without pigment, was aged by natural and accelerated methods. Tensile and impact properties and melt index were evaluated before and after aging, and also after recycling. The rupture elongation of the recycled material very good, showing the recycling potential of this material. Tensile modulus and tensile strength were not affected by processes to which the blend was submitted. The impact strength of the recycled material showed a decrease after ageing.
