ETFE: Ethylene-Tetra-Fluoro-Ethylene
ETFE is an ultra strong fluorine polymer that is corrosion and stain resistant, nonstick and self-cleaning. It retains its clarity (and thus also its superior light transmission) which guarantees that these solar panels work for a long time
Benefits of ETFE:
1: Durability
ETFE film is durable and does not discolour over time even when exposed to chemicals, heat, ultraviolet light or extremely low / high temperatures. Nor does it become structurally weaker with time.
2: Long service life
ETFE is robust, which means only small risks of degradation when exposed to pollutants in the environment.
The fact that ETFE is included in flexible solar panels is fairly new, but ETFE has been used in other appliances where it has shown the same good properties as mentioned in points 1 & 2. Research has shown that ETFE retains its strength, clarity and self-cleaning properties for at least thirty-five years
3: Breach limit:
The breaking point measures how much, at most, a substance can be subjected to ignition or drawing before it breaks. ETFE films are very elastic (up to 600% at the breaking point) but are structurally resistant in all situations
4: Stain resistant and easy to clean
Due to its low coefficient of friction, dust and dirt do not stick to the ETFE film. The surface properties of the ETFE film, e.g. not adherent, makes it difficult for pollutants to get stuck there.
5: Light transmission
ETFE is a transparent lightweight film and is delivered as a single-layer membrane, 0.5 mm thick. It is a great alternative to glass, perfect for flexible solar panels.
6: Fire assessment
National and international fire standards assess ETFE as self-extinguishing.
