thicknesspunctureair permeability

Overview C910H Integrated Air Permeability, Puncture and Thickness Testing System employs the volumetric method for gas permeability testing and mechanical principles for puncture strength and thickness measurements. It is specifically suitable for measurement of air permeability, puncture strength and thickness of battery separators and related polymer films.
