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.

Result: PE Envelope Separator increases the battery life of batteries
