HOMELead-acid storage…Types of separators

Separator for car batteries・motorbike batteries

General-purpose type CV-30

  • Low cost
  • Water resistance
  • Acid resistance
  • Porosity (micro pores)
  • Oxidation resistance

It is a low-cost general type separator by which you can obtain adequate battery performance in use.

High performance type NB-25

  • Water resistance
  • Acid resistance
  • Porosity (micro pores)
  • Oxidation resistance
  • Low electric resistance

As the electric resistance is low, the engine start ability improves. Especially the engine start ability is high at low temperatures and after long storage.

LT-30 Long-life type LT- 30

  • Long life
  • High temperature resistance
  • Water resistance
  • Acid resistance
  • Porosity (micro pores)
  • Oxidation resistance

Compared to General type CV-30, it is a separator usable for a long time inside batteries.

Envelope CV-30 NB-25 LT-30

It is a type of product that wraps electrode plates inside batteries like an envelope.
Our separators can do envelope processing in any separator.

Stationary・Electric vehicles (industrial batteries) separators

Electric vehicle・Special vehicle LT-40
High reliability long-life type STK-50,ST-60,80,100

  • Long life
  • Water resistance
  • Acid resistance
  • Porosity (micro pores)
  • Oxidation resistance
  • Durability
  • High temperature resistance

This is a much longer life type than LT-30 above and there is a lineup of separators with thickness between 0.40mm and 1.00mm.
They are separators durable for repeated battery charge and discharge and they have certain thickness so they are untearable inside batteries and can withstand severe use.
