ETFE coatings are a copolymer of Ethylene and TetraFluoroEthylene better known as Tefzel®. ETFE coatings are designed to give uniform thick or thin film coatings and are based on a modified ETFE. Changes in physical properties by radiation include reduced elongation while tensile strength remains unchanged. Stiffness is increased and electrical losses are increased.

These changes are independent of whether radiation took place in air or nitrogen. In the case of flex life however, a difference exists in that radiation in nitrogen gives a greater flex life than an equal dose in air.

This type of coating should be considered for a broad range of applications where you need the benefits of the following qualities:
High performance thermal
Chemical and electrical properties
Outstanding mechanical toughness
