Micro-porous Membrane/Porous Film
Micro-porous Membrane/Porous Film
Membranes with countless continuous pores that are generally smaller than the diameter of raindrops (100 – 3000μ) and larger than the diameter of vapor (0.0004μ).
Commonly known as breathable waterproof membranes, they are used in raincoats, sportswear, and shoes, etc.
In the field of polymers, this principle is applied in the technology for ion exchange membranes and high-performance filters.
