Excellent chemical and thermal stability.
Beside a porosity of more than 40 percent and a uniform pore size, separator film must have excellent properties concerning chemical and thermal stability, tensile strength, low shrinkage and thickness (dimensional strength).
To reach these properties, SML delivers extrusion lines working on a dry process basis. Compared to separators produced in a wet process, the pore structure of separators produced in a dry process is more open and consistent – and therefore these films are better suitable for higher power density.
Eco-friendly – very low consumption of raw materials
Due to the advantages of the dry production technology, SML’s extrusion lines for separator film work very cost efficient and eco-friendly.
Compared with the more complex wet process, it is not necessary to use solvents to excavate the low-molecular material. The separator film leaving SML’s line can be a one or three layer film on PP or PE-base, in perfect quality for further processing steps.
