Polymer Fiber Spinning, Wet Spinning Spinneret
Introduction
We offer hollow fiber membrane spinnerets for non-solvent induce phase separation methods. The spinneret is made of a high quality stainless steel, with the highest connectivity reaching 0.003mm.
Suitable materials
PVDF (Polyvinylidene Fluoride), CA (cellulose acetate), PVC (Polyvinyl chloride), PES (Polyethersulfone), PSF/PSU (Polysulfone), PA (Nylon, Polyamide), PAN (polyacrylonitrile)
- Conventional design
- Independent design
We can provide a design that allows the spinneret to be removed, replacing conventional designs where each spinneret hole cannot be independently replaced and disassembled. If one has a quality problem, the entire spinneret needs to be either repaired or scrapped. Our spinnerets are designed independently, with each hole able to be individually replaced if needed.
What is a Nonsolvent Induce Phase Separation method?
Non-solvent induced phase separation, also known as NIPS, is the process by which a polymer is dissolved into a solvent in order to form a homogenous solution. A reagent is then added as an extracting agent that is more miscible with the solvent, thereby extracting the solvent in order to form a two phase structure with the polymer as a continuous phase and the solvent as a dispersed phase. The solvent is then removed in order to obtain a new polymer with a specific pore structure.
