Innovative Films & Membranes

Manufacturing Technologies

LiSO films are made by dry and wet processes, consisting typically of extrusion, casting, and orientation units. The dry process extrudes polymer melts via a film die to produce membranes or oriented films; opaque, clear or porous in character. LiSO DRY FILMS are Eco-Friendly, composed often of finely dispersed multiphase morphologies with superior strengths at an extremely thin gauge. 

The wet process is used to produce porous film products, by employing thermally induced phase separation and nonsolvent induced phase inversion techniques. It extrudes polymer solutions, which is stretched and extracted, to produce an oriented nanoporous film. 
LiSO WET FILMS are Eco-Friendly, yet superior in strength, porosity, uniformity, and resistance to heat, voltage, environment, and chemicals.
