Capillary Fiber
Polyimide coated
Product description
- high-precision optical capillary fibers made of high-purity quartz glass
- Micro/nano level (300nm ~ 100µm) inner holes fabrication by precise control of air pressure
- very small deviation of the inner and outer diameter
- For customers in the scientific and engineering, medical treatment, industrial and fiber optic sensing sectors who require accurate measurement and control of liquids and gases
Properties of the fiber
- smooth inner wall has low resistance and high internal pressure consistency, and performance in liquid movement
- multi-stage online measurement ensures the stability of the inner and outer diameter even with a few hundred meters of capillary fibre
Properties of the polyimide polymer
- good resistance at low and high temperatures
- good mechanical strength and excellent general performance
- self-extinguishing with low smoke development
- Coefficient of thermal expansion close to that of quartz material
- self-lubricating
- non-toxic and biocompatible
- resistant to almost all organic solvents, some inorganic acids and hydrolysis
