Help me identify a filament's material (lemmy.sdf.org)

I found a small length of filament in the parts bin. I don't know what it is, and nobody else here does, or remembers ordering it. I'm pretty sure it's a sample that was sent by Prusa when we ordered the printer, and it's probably not a special material.

It's feels "gummy" and a lot softer than PLA, but not really rubbery either. And I tried printing something with it at 230C as if it was PLA and it's clearly not hot enough: it's able to flow out of the nozzle but it barely sticks to the bed.

Any idea what it could be?

And notwithtanding that the damn stuff is around $78 for a kilo of filament! My other guess was polyethylene (HDPE). These two are pretty similar mechanically, both being polyolefins, but polypropylene melts at a higher temperature.
