ACA Permi Lab LP 100

Air permeability analyzer for low porous materials

Fast and easy air permeability measurement

Air permeability is an overall measurement of process performance and structural uniformity of produced material. In some technical advanced materials, the permeability or breathability is the key property of the end use. Often these materials (separator films, membranes, breathable films etc…) are very low porous and thus out of the measurement range of common instrumentation. Furthermore, the measurement of low porous material can take very long using traditional instruments.

ACA Permi Lab LP 100 is designed for fast and easy air permeability measurement of low porous materials.

Benefits of ACA Permi Lab

  1. Wide measurement range:
    • Bendtsen, ml/min 5 – 400
    • Coresta, ml/min 1 – 100
    • Gurley, s 30 – 2000
    • Others on request
  2. Fast measurement; Less than 10 sec even for very low porous materials
  3. Very easy to measure CD profiles

Best applications Films & Engineered materials

Battery separator films (BSF)

Air permeability measured typically as Gurley unit is one of the key characteristics of a battery separator film. The separator with uniform permeability is essential for the long cycle life of a battery. Variations in permeability will result in uneven current density distribution, which may be a risk for the whole battery. ACA Permi Lab can measure repeatability and fast the Gurley values of the BSF-film either from single point or CD profile

Breathable films

Breathable films are used extensively in diapers and food packaging. For the enduser, the quality of the film needs to be constant and breathability variations minimized. ACA Permi Lab can rapidly measure breathability values of the film in a repeatable way. Its high speed makes profile measurements an easy task.
