All national and local building codes now require metal ducting for clothes dryers. It's ideal to use the stiff (rigid) aluminum tubing pieces. This type of tubing does the best job of resisting the collection of lint in the duct. You can use flexible aluminum ducting instead, though it's far more prone to collecting lint inside.
White vinyl ducting is dangerous. It is flammable and, if ignited by the dryer, it may burn and cause a house fire.
