Plastic 50g ETN

ETN Plastic, about 50g VS 8mm steel plate.

Plasticier is 15% PI/PIB (Polyisobutylene)

But further tests show that mineral oil + PIB are better and enable to decrease the ration to about 12%.

ETN is less easy than PETN to plasticize.
And even if wikipedia or other unexperimented documents said there are no degradation in storage, ETN is less stable chemically and is weaker to strong acids than PETN, I can see that in nitration.
In your hands, you can see that PETN is more "synthetic" so probably more stable chemically.
