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
