Due to the higher cost position of copolyester, it was substituted for PC/PBT in the consumer disinfectant testing. 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.

Developed to meet these challenges, Edgetek ET8900 CR thermoplastics show improved chemical resistance to common consumer disinfectants compared to PC/ABS, PC/PET and PC/PBT. Improved Chemical Resistance $$$$ $$$ $$ $ FR PC/ABS FR PC/PET FR PC/PBT FR Edgetek™ CR
