Application:
Used as separators between anode plates and cathode plates in valve regulated sealed lead acid batteries, they have functions of preventing short circuit, absorbing electrolyte and providing need of water refilling and maintenance.

Packing:
Supplied in rolls or sheets wrapped with plastic film and contained in cartons.
