Product Applications
Product Features
Polyimide optical fiber, also known as polyimide-coated fiber, is a type of optical fiber that uses polyimide as the coating layer. Polyimide is a high-performance polymer material with excellent high-temperature and low-temperature resistance, good mechanical strength, and outstanding overall performance. It can withstand temperatures up to 380°C, with a long-term usage range of -200°C to 300°C. Some forms of polyimide have no distinct melting point and offer high insulation performance, with a dielectric constant of 4.0 at 103 Hz and a dielectric loss of only 0.004 to 0.007.
Characteristics of Polyimide Optical Fiber
The primary characteristics of polyimide optical fiber include high-temperature resistance, hydrogen corrosion resistance, and radiation resistance. The use of a polyimide coating enhances the thermal performance of the fiber coating layer, extending the fiber's lifespan in high-temperature environments. Additionally, polyimide optical fibers possess excellent radiation resistance and mechanical properties, maintaining high strength even in irradiated environments.
Applications of Polyimide Optical Fiber
Polyimide optical fibers are widely used in special environments such as high temperatures, chemical corrosion, and radiation. They play a significant role in fiber optic sensing, especially in environments with high temperatures, high pressure, low temperatures, electromagnetic radiation, underwater usage, and medical interventional treatments.
Production of Polyimide Optical Fiber
The production process of polyimide optical fiber typically involves the preparation of the fiber core and cladding, followed by the application of the polyimide coating. The coating process is time-consuming, resulting in lower production efficiency. Additionally, due to the high modulus of polyimide, the coating cannot be stripped using conventional wire strippers.
