Battery Polyethylene (PE) Separator Film
Standard roll 85mm x 60m, custom sizes on request.
Generic separator used in separating lithium ion battery cathode and anode. Lower melting point than more common PP separators which may be beneficial in some cases with self shutting cells.(Please be aware that 3 layer PP/PE/PP separators are also available, check Celgard 2320 and Celgard 2325)
Product characteristics:
1. Uniform pore size distribution
2. Low obturator temperature
