It can be seen that the PC/ABS and PC/PET samples failed to survive the disinfectant exposure and produce a testable sample. With regards to PC alloys, the general trend of increasing chemical resistance was observed in order of PC/ABS < PC/PET < PC/PBT, which was expected based on previous research and the marketing literature of PC blend manufacturers.4 However, the Edgetek ET8900 series clearly demonstrated the best ESCR performance against the household cleaners.
