CoexFlex 60D is a thermoplastic copolyester elastomer (TPC). It flexes like TPU, but prints faster and has more strength, heat resistance and chemical resistance. 60D is the firmest grade in the CoexFlex line. Use it for parts that need to flex and bend repeatedly: grips, protective cases, seals, gaskets and functional prototypes.
