S.no. | PROPERTY | PE SEPARATOR | PVC SEPARATOR | BENEFITS OF PE SEPARATOR |
---|---|---|---|---|
1 | Electrical Resistance (ohm/cm2) Industrial/ Auto | 0.45 max. 0.25 max. | 0.75 max. 0.75 max. | Low Electrical Resistance improves electrical performance of the battery. |
2 | Porosity | 55-65% | 30-40% | High Cranking Power: More Current with PE. |
3 | Average Pore Size | Less than 1 micron | 20-25 micron | Eliminates self discharging problem and also eliminates Lead and Antimony growth. |
4 | Acid Displacement | PE separators has low acid displacement to the order of 0.01 ml/cm2 | It is 0.08 ml/cm2 in PVC | Less Acid Displacement means more reserve capacity: Provide maintenance-free performance. |
5 | Oxidation at high temperature | PE separator has better resistant to oxidation than PVC separators. | No appreciable resistant to oxidation and also release chlorine gas at higher temperatures | Enhances Service Life of Battery. |
6 | Shorts due to Shedding | PE envelope separator eliminate Bottom shorts and Side Shorts | PVC separator has shorts | No complaint of one or two cells failure during the battery life due to PE separators. |
7 | Cold discharge | PE separator has cold discharge of 9.11 volts | PVC separator has a cold discharge of 8.3 volts. | No starting problem even in morning during cold weather. |
