Performance Membrane Separators

Sigma is working to develop new and improved battery separators using its DryFab™ Vapor Deposition process to uniformly functionalize microporous and nano-fiber media to improve surface wetting properties - as well as performance at higher temperatures.

Low ESR, Low Dissipation Factor, Film Capacitors

Sigma, using its PML Technology is able to produce capacitor films that exhibit lower dissipation factor and significantly lower ESR compared with conventional polypropylene capacitors. The result is greater reliability and performance at higher temperatures.
