Key Advantages

✅ Stable Film-Forming Performance

Wide solvent tolerance and adjustable viscosity. Precisely controls pore size and membrane microstructure for consistent membrane quality.

✅ Intrinsic Hydrophilic & Low Fouling

Low water contact angle resists organic and protein adsorption. Delivers higher stable flux and longer service life for water filtration.

✅ Excellent CO₂ Selectivity

Ideal for CO₂/CH₄ natural gas decarbonization, flue gas CO₂ capture and syngas hydrogen purification.

✅ Sustainable Bio-Based Material

Derived from renewable forest resources, supporting low-carbon and eco-friendly manufacturing standards.

Applicable Processes

NIPS

1. Non-Solvent Induced Phase Separation

Compatible with acetone, DMAc, DMF and mixed solvent systems. Works with PEG and glycerol porogens for flat-sheet MF/UF/NF membrane production.

VNIPS

2. Vapor-Assisted Phase Separation

Controls surface pre-evaporation and humidity to eliminate finger-like pores, producing uniform sponge-like membranes for high-end precision filtration.

Dry-Wet Spinning

3. Dry-Wet Spinning Process

Mass production of hollow fiber membranes for MBR, water treatment and dialysis modules. Supports braided reinforcement for enhanced mechanical strength.

Electrospinning

4. Electrospinning Process

Produces high-porosity nanofiber membranes with excellent adsorption performance for dye removal, advanced wastewater treatment and functional filter media.
