The company's nylon pleated filter cartridges are made of natural hydrophilic nylon filter membrane and polypropylene components. They are produced in a Class 100 clean environment using advanced hot melt sealing technology. They have excellent chemical compatibility, no fiber shedding, uniform pore size, and strong flexibility. They do not contain any adhesives or surfactants. At the same time, the surface can be modified with a positive charge to fully meet the requirements of filtration (100% integrity testing, absolute filtration accuracy, high retention rate of sterilizing grade filter cartridges, compliance with GMP standards, etc.). They are widely used in the filtration of strong alkali, weak acids, and organic solvents.
