Key requirements for high-temperature service

High ambient temperature shortens float life. This series is engineered to resist collapse and aging under sustained heat, helping maintain separator structure and plate-group compression across wide temperature swings.

A density of 165 g/m²·mm and thickness of 1.0–2.5 mm at 10 kPa provide electrolyte capacity for extended discharge, while 0.5–2.0 μm fibers help retain puncture and dendrite resistance at elevated temperature.

01

Sustained heat

High ambient temperature shortens float life. The structure resists collapse and aging under sustained heat, helping maintain plate-group pressure.

02

Extended discharge periods

A density of 165 g/m²·mm with 1.0–2.5 mm thickness at 10 kPa provides electrolyte capacity for extended discharge.

03

Temperature swings

Fine 0.5–2.0 μm fibers keep puncture and dendrite resistance even when hot; elastic recovery holds compression across large temperature swings.
