Daramic® HP-X™
Daramic HP-X is a high-performance polyethylene battery separator designed for starting, lighting & ignition (SLI) and enhanced flooded (EFB) lead-acid batteries. The patented cross negative rib profile & special formulation deliver improved cycle life by providing excellent puncture resistance, slowing of dendrite shorts &better acid mixing. It also improves efficiency & yield during battery assembly.
Features:
- Unique cross negative rib profile better supports enveloping
- Excellent for high under-hood temperature applications
- High puncture and oxidation resistance
- High porosity for lower electrical resistance
- Available in a wide range of product profiles
- Available with glass mat for heavy duty applications
Benefits:
- Improved yields and lower scrap rates
- Lower risk of battery failures associated with dendrite shorts, especially in batteries designed for high power and narrow plate spacing (<0.80mm)
- Improved acid mixing with longer life, especially under Partial State of Charge operation
- Improved overall battery electrical performance
