Range vent hood pipe
According to IRC, the duct must be made from galvanized steel, stainless steel or copper. It must have a smooth interior, and be air tight. Which means you're not going to want to use a flexible product for this application, especially that flexible plastic crap. Instead, you'll want to use rigid duct like this.

And you'll want to make sure you seal all seams with mastic or tape, that's designed for the purpose.
If you're not sure what building code is used in your area, the safest bet is to simply follow the installation instructions provided by the manufacturer of the range hood.
