3D space inside of non-woven fibers, capture small particle directly, high efficiency, low cost, large capacity of dirty particles.
Low temperature resistance ( PP 94 °C)(PE 135 °C)
Micron rating: 0.5-800um
Excellent resistant to hydrolysis, acids and alkalis.
Smooth surface, more defined pore size and good air permeability
Lower fiber release, Lower density, High mechanical characteristics
