Wet Membrane

We imported the most advanced production line with higher hardware level than other domestic lines in China, based on the Synchronous stretching technology and film manufacture experience, by improved raw material formulation, we realized the precisely control of the whole production procedure. Our simultaneous biaxial stretching WET separator has plenty of advantages: good uniformity, high stretching ratio, high mechanical strength, pore-size well distributed, high porosity and good heat stability. We'll take position at the top level ultra-thin separator (7-16μm) market, substitute the foreign separator and better satisfy the coustomers' request about high energy desity of Li-ion battery.
