Although "poly" tennis strings are very durable, you can still break them by "shear" force applied when you hit an off-center shot along the edge of the frame. The edge of the frame at the grommett is very rigid, so the potential shear force is high if you hit the string hard right near that point.
If you are a "string breaker" you have to use either a hybrid stringjob with poly on the mains and something softer on the crosses, or even consider Kevlar for the mains, or poly on the whole stringbed. But a poly can still break via this shear mechanism so do not be surprised if you break a poly string after 1 match when you thought the string would last several months.
