Nynas naphthenic oils are ideally suited for polyethylene separator production.
NYNAS NAPHTHENICS - BATTERY SEPARATORS
- Highly refined naphthenic oils facilitates pore formation in the polyethylene matrix.
- Hydrotreated naphthenic oils in the separator minimize chemical reactions that could contribute to residual formation inside the battery.
- The low viscosity index of naphthenic oils support polymer processing and may allow for lower process temperatures.
For lead acid separators, selected naphthenic grades can prolong service life and ensure problem-free maintenance for industrial batteries thanks to their low content of impurities. They also ensure efficient incorporation and lubrication of the polymer melt during the processing step. Nynas’ naphthenic oils allow for elevated process temperatures in lithium ion separators and their high compatibility with the polymer contributes to excellent mechanical properties of the separator.
