ETFE tight-buffered fiber

Product introduction

Product introduction:


ETFE is a high-performance engineering plastic material, which is a copolymer of ethylene and tetrafluoroethylene with particularly excellent comprehensive properties. For example, it is excellent in heat resistance, low temperature resistance, flame retardancy, electrical insulation and chemical resistance, and has unique non-adhesive and low friction properties. The tight-buffered optical fiber produced by using ETFE as a buffer material inherits the above-mentioned excellent properties, and this kind of tight-buffered optical fiber can be used in fields with special requirements such as high temperature resistance and flame retardant.


Features:


1. Reach the highest flame retardant grade UL94 V-0


2. Remains soft at low temperature


3. Long-term work at a temperature of 150 ℃ to maintain perfect performance


4. Final protection of the optical fiber



Product features

1. Temperature and pressure monitoring


2. Communication connection in harsh environment


3. Connect the optical communication module and the optocoupler


4. Effectively prevent the erosion of water vapor, fuel oil, acid and alkali and solvents to the optical fiber, and ensure the transmission performance of the optical fiber
