SepraTek has an innovative Thermally Induced Phase Separation (TIPS) process that enables the production of chemically stable, large-diameter porous hollow fiber membranes without stretching process. Sepratek's TIPS process can also produce hollow fiber membranes with various porosities as well as a robust hollow fiber membrane through braiding the hollow fiber with a high strength of polyester yarn.
Sepratek’s TIPS process can produce chemically stable materials that cannot be manufactured by the DIPS process into hollow fiber membranes. Sepratek’s TIPS spinning systems are designed and manufactured by engineers with many years of field and experimental experience.

The TIPS-based manufacturing facility is designed and manufactured using valuable know-hows acquired through many years of in-house R&D efforts, such as twin-screw extruder design, supply method of materials to the extruder, piping design from the discharge port to the spinning nozzle and spinning process for producing of a hollow fiber membrane with a porous structure on its outer surface. A brief description of the manufacturing facilities is as follows.

SepraTek also supplies a batch-type of TIPS spinning equipment that uses an autoclave tank for preparing of high-temperature dope solution instead of the twin-screw extruder, and SepraTek can offer customers consultation on the manufacture of membranes. The membranes that can be manufactured using the manufacturing facility are as follows;

SepraTek’s hollow fiber membrane manufacturing machine is designed and manufactured based on the expertise of Sepratek's engineers who have accumulated wealthy experiences from on-site R&D for many years. Hollow fiber membranes are manufactured by NIPS (Non-solvent Induced Phase Separation) and can be manufactured in various inner diameters and thicknesses through precise control, and can also be customized up on request from customers. A brief description of the NIPS hollow fiber manufacturing facility is as follows;

SepraTek offers membrane fabricating equipment for R&D designed to achieve fast and accurate results as manufacturing variables change. In addition, SepraTek offers its customers consultation on membrane manufacturing technology such as module potting machine, potting adhesive supplier, module cutting machine, and spinning nozzle. Membranes that can be manufactured using the manufacturing facility are as follows;
