	These are high-performance plastic materials such as [https://en.wikipedia.org/wiki/Polytetrafluoroethylene PTFE] ("Teflon") [https://en.wikipedia.org/wiki/ETFE ETFE] (Tefzel"). They have very interesting properties such as UV resistance, elasticity, resistance to corrosion from most substances and very good high temperature performance. Fluoropolymer foil is useful as [[greenhouse]] covering and for [[Aluminum Extraction From Clays]]. The UV resistance of these materials results in long life, with up to 30 years reported with minimal degradation.

Fluoropolymer foil is useful as [[greenhouse]] covering and for [[Aluminum Extraction From Clays]]. The UV resistance of these materials results in long life, with up to 30 years reported with minimal degradation.

	Also, UV transmission leads to a more "natural" light spectrum inside the greenhouse, suppressing microbes that may otherwise survive if UV light is blocked off. Fluoropolymers are slowly catching on as greenhouse covering but are still much more expensive than current alternatives such as polyethylene and [[polycarbonate]]. This may be due to lower overall production volume rather than inherently higher cost of the process. Drawbacks include high cost (10x that of polycarbonate), susceptibility to puncture holes and movement/wind, which is why fluoroplastic foil is often inflated as cushions (see images: "Pillow Dome" and "Eden Project"). Thicker membranes are possible but much more expensive.
