ETFE Tight Buffered Fibre

ETFE is an engineering plastic with high performance, and it is a copolymer of ethylene and tetrafluoroethylene, with excellent general property, such as outstanding resistance to heat and flame, low temperature resistance, insulation resistance, chemical resistance, and particular less viscous performance. Therefore, ETFE tight buffered fibre also has above-mentioned performance, and can be applied to heat resistance, flame retardant and other special field.All of YOFC ETFE tight buffered fibre have past 100kpsi proof-test, with a primary coating of UV-cured acrylate to a diameter of 250μm and a secondary ETFE buffer to 900μm.The primary coating and secondary buffer could be mechanically removed to the 125μm glass diameter in one step, which could be used for direct termination with connectors. Also it permits mechanical stripping in short lengths (about 15mm) to remove the secondary buffer and leave the 250μm primary coating intact, which is available for splicing to similar buffered fibres from loose-tube gel-filled cables.
Applications
  • Temperature and stress monitoring
  • Hazardous environment connectivity
  • Linking optical communication modules/optical link couplers
  • Providing an effective resistance to water vapor, oils/fuels, acids/alkalis, and solvents, which could adversely affect the fibre's signal transmission capabilities
Characteristics
  • Highest flame retardant grade of UL94 V-0
  • Flexibility at low temperature
  • Retention of properties after aging at elevated temperatures up to 150℃
