Air permeability analyzer for low porous materials
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.
ACA Permi Lab LP 100 is designed for fast and easy air permeability measurement of low porous materials.
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 with repeatability and fast the gurley values of the BSF-film either from single point or CD profile
Breathable films are used extensively in diapers and food packaging. For the end-use the quality of the film needs to be constant and breathability variations minized. ACA Permi Lab can measure with repeatability and fast the breathability values of the film either from single point or CD profile
