Solupor Membrane

Solupor® membrane is specially engineered with Ultra High Molecular Weight Polyethylene, using a unique patented proprietary manufacturing technology. This membrane has excellent performance characteristics, featuring a combination of high porosity, chemical stability, and good mechanical properties. Combined with the available thickness ranges, Solupor membrane is suitable for a full range of demanding applications requiring a high performance hydrophobic separator.

Different than most other porous separators, Solupor membrane has a unique pore structure, being highly tortuous, with the membrane itself having a fibrillar structure somewhat similar to nonwovens. This makes these membranes especially suitable for fast filling with organized electrolytes.
