Hollow fibers (< 0.5 mm), capillaries (0.5 – 3 mm) and tubes (up to 10 mm) can be processed with our piston spinning equipment. The parameters of extrusion can be varied from RT up to 320°C and from 1 to 300 bars. Material amounts ranging from 10 to 500 g can be processed into membranes. By using suitable material combinations thermally induced phase separation can be performed to manufacture capillary membranes with a controlled pore size. Due to low material consumption expensive materials like biopolymers, noble metal- doped materials or valuable ceramics can be processed.
