Field cracking in some instrument panels (IP) manufactured with a competitive grade of polycarbonate/acrylonitrile-butadiene-styrene (PC/ABS) material was observed in high temperature/high humidity geographies. OEMs and tier molders are: 1) questioning the thermal and hydrolytic stability of the various suppliers' PC/ABS resins, and 2) converting to grades with advantaged stability.A study was undertaken to compare the thermal and hydrolytic stability of two suppliers' high flow PC/ABS resins. Materials were aged at 90C/95% relative humidity up to 1000 hours. Samples were tested to compare the retention of properties.This paper will discuss the experimental procedures, resulting data, and the common factor in the PC/ABS resins showing the best stability.
