I have heard that there is a waterproof variant of MDF although never knowingly seen it. Maybe this is what you saw?

IIRC there is a fire resistant version that looks like this...
MDF or chipboard? The water "resistant" chipboard used in bathrooms looks like this.
It sounds very much like waterproof MDF to me.
It has a green tint to the shavings and dust when you cut it and the stuff I have used has a green painted stripe on the edge.
If anyone is wondering I can confirm that it is waterproof and all but the thinnest strips have failed to warp after being left outside in a water filled bin for over 2 years!
