EVA Heat Shaping Test

I've just cut some of the major pieces for an EVA foam armor project, and I wanted to get a feel for different methods for how to heat-shape the material. Here are my results:

The wavy piece was under a heat gun at high settings, and the round piece came from a 250*F oven after ten minutes. The oven piece seemed to warp a little on the corners from gravity, but for my project that might actually be an advantage. The oven piece gets even heat, and this bends very evenly. It comes out warm, but manageable even with bare hands; after some shaping, it cools quickly and gets quite rigid. I think both pieces are actually more rigid after heating; I wouldn't be surprised if this also shrinks them very slightly. I can see using the heat gun for fine points and touch-up, but I prefer the oven for large pieces. I wonder if the heat gun scorch marks could also be avoided by using a lower setting or trying for a more gradual, even heat. 

What I'm Playing:
