ETFE is a manmade fluoropolymer which stands for ethylene tetrafluoroethylene , which has attained its position as an efficient architectural material. The appearance of ETFE is like a transparent sheeting material type , which can be employed instead of glass and plastic that are hard in nature.
The fluorite is combined with other two compounds namely trichloromethane and the hydrogen sulfate. The above mixture , by the process of pyrolysis , produces chlorofluoroethylene , which is later combined with ethylene to make ethylene tetrafluoroethylene or the so called ETFE.
ETFE is regarded as one of the exciting material in building construction industries. It has favored the construction world with the potential it offers.
The properties of ETFE materials reflects the advantages it provides. ETFE possess a non-sticky surface , which gives them a self-cleaning as well as recycling capacity.
The combustion of material would result in the emission of hydrofluoric acid (HF) which is highly toxic and corrosive in nature. This force us to undergo a proper disposal for this material.
Sharp edges create punctures in these materials , hence it is commonly used as roofing or as a cladding material. It is stretchable , hence a variation in size can be compromised. This advantage is more effective when ETFE are used as a roof material.
The tensile strength of ETFE is 42N/mm2 with 89 K to 423 K as its working temperature. It is found highly ultraviolet light resistant when subjected to a weathering test done under high acceleration. The test showed no kind of deterioration in the material.
