Using this strategy, it is possible to obtain new UV-curable fluoropolymer resins showing good solubility with several types of organic... 

Some fluoropolymers prepared by DT with iodo-compounds have already been commercialized such as Daiel, Viton, and Technoflon. Such fluoroelastomers may find applications in high technology such as in O-rings, gaskets, hoses, transportation, medical devices, and electronics. The control of the architecture and functionality of the polymer chains makes possible the preparation of peroxide curable fiuoroelastomer with improved properties as well as the development of advanced fluorinated thermoplastic elastomers. Another application of functional fluoropolymers prepared by DT with iodo-compounds is the preparation of membranes for fuel cells. 

Some atmospheric plasma treatments allow in-line surface modification of almost any wire insulation material. Examples include polyamides, polyesters, and the fluoropolymers most difficult to treat. A treated surface can then accept inkjet printing for marking purposes. Table 5.13 shows a comparison of the marking durability on ethylene tetrafluoro-ethylene copolymer (ETFE) and fluorinated ethylene propylene copolymer (FEP) for untreated (U), flame treated (FI), and plasma treated (PI) conditions. Some wires have been cross-linked by irradiation (IR) to enhance cut-through resistance of the insulation. Wire suppliers have been identified in each case and all ink was UV curable.
