Folded filter is made of polyethersulfone. The polyethersulfone is the most advanced microporous membrane in the world. The polyethersulfone membrane pores account for more than 80% of the membrane volume. The pores has a microporous geometry, thus it can raise the filtration efficiency and throughput of the highly required solution.
The filter is made of polyethersulfone and polypropylene, no adhesive, suitable for chemical and pharmaceutical industry with strict requirements.
Main features: excellent hydrophilic properties, free of surfactants and surface lubricants, providing a high level of filtration precision and flux for filtration solutions, can be applied in many PH enviroment, high rate of retention, excellent chemical resistance and thermal stability, good strength, resistance to forward and reverse pressure shock.
