LAN CABLES

摘要

Use in LAN cable applications, as materials for the coating of the primary cable and for the external jacket, of TFE thermoprocessable perfluoropolymers comprising perfluoroalkylvinylethers in the following amounts, expressed as per cent by weight on the total of the monomers: a) 0-5.5 % of perfluoromethylvinylether (PMVE); b) 0.4-4.5 % of perfluoroethylvinylether (PEVE) and/or perfluoropropylvinylether (PPVE); when a) is present, then a) + b) ranges from 1.5 % to 5.5 % by weight on the total of the monomers; optionally c) 0-6 % of hexafluoropropene (HFP); the TFE amount being the complement to 100 % by weight.
