Optical Performance Comparable to AF2400
Refractive index lower than water: A domestic alternative material to AF2400 that enables total internal reflection of liquid-core waveguides (LCW), significantly improving the sensitivity of spectral detection (such as Raman and UV-Vis spectra).
High light transmittance (>95%): Supports applications from deep ultraviolet to near-infrared bands, compatible with optical sensors and microfluidic chips.
Ultra-high Gas Permeability
Leading permeability of oxygen, hydrogen and carbon dioxide: Comparable to AF2400, suitable for vacuum degassers, gas-liquid microreactors, and dissolved gas monitoring of transformer oil.
Excellent liquid-gas separation: The "tube-in-tube" design achieves uniform gas dissolution and improves chemical reaction efficiency (e.g., hydrogenation and oxidation reactions).
Exceptional Chemical Corrosion Resistance
Resistant to strong acids, strong alkalis and organic solvents.
Customized Services
Inner diameter: Starting from 76 microns (matching the minimum specification of AF2400), cutting available on demand.
Flexible wall thickness: Starting from 25 microns to meet mechanical strength requirements of different scenarios.
Diverse product forms: Full range of products including powder, solution, film and tubing to satisfy scientific research and industrialization needs.
