No, that tire is no good anymore.
However, this will happen to you again if you don't follow a couple of precautions regardless of brand of tire.
First, give the tires time to warm up before you start pushing it. When the rubber is not uniformly heated i.e. the surface is hot and the lower carcass is still cold you are going to experience chunking. Let the tires heat up for a couple of laps before you start pushing.
Your second comment about corner entry speed is probably true. If the car feels like it's understeering then you are grinding off the outer edge (assuming your run the stock suspension alignment). Try to slow your corner entry, which allows you to properly position the car so that you can exit faster which will be quicker around the track and less of this type of wear on your tires.
