s, in terms of releasing hydrofluoric acid (HF). HF is extremely corrosive and toxic, and so appropriate caution must be exercised. ETFE film is self-cleaning (due to its nonstick surface) and recyclable. It is prone to punctures by sharp edges and therefore mostly used for roofs. As a film for roofing it can be stretched and still be taut if some variation in size, such as that caused by thermal expansion, were to occur. Employing heat welding, tears can be repaired with a patch or multiple sheets assembled into larger panels. ETFE has an approximate tensile strength of 42 MPa (6100 psi), with a working temperature range of to ( to or to ). ETFE resins are resistant to ultraviolet light. An artificial weathering test (comparable to 30 years’ exposure) produced almost no signs of film deterioration. ETFE systems can control light transmission through the use of frit patterns printed on the foil. Thermal and acoustic insulation can be incorporated into an ETFE structure via the use of multi-layer systems which use low-pressure air pumps to create ETFE "cushions".
