3.1
Microporousmembrane
Pore size between 5.0 nm and 1.0 mm.
3.2
Porosity porosity
The ratio of the volume of the pores to the volume of the membrane, that is, the volume percentage of the pores in the volume of the unit membrane, which is the density of the raw material resin and the product
Related, including open porosity and closed porosity.
3.3
Density density
The mass of the substance contained in the unit volume at the specified temperature.
Note. Units in kilograms per cubic meter (kg/m3) or grams per cubic centimeter (g/cm3). When reporting density, indicate the density units and temperature used. E.g,
Kg per cubic meter or grams per cubic centimeter, t ℃.
