Description

Description of PVDF Membrane Filters

PVDF membrane filter has good heat resistance and chemical stability. PVDF filter can withstand high-pressure steam sterilization at 128-142℃ and can withstand strong acids, aliphatics, aromatics, alcohols, aldehydes, ketones, ethers, and other organic and inorganic solvents. The membrane has stronger corrosion resistance than the polypropylene membrane. Both sides of the membrane are completely covered, no fibers are exposed, the surface pores are densely distributed, the pores are round and oval, and the pore size is different. As the pore size of the membrane decreases, the membrane binds to low molecular weight proteins more firmly.

It has excellent chemical compatibility, including corrosion resistance, oxidation resistance, and heat resistance. Its broad chemical compatibility allows the filter to accommodate a wide range of applications especially those requiring a high flow rate.  The flow rate of the membrane is lower than the PES membrane.

PVDF membrane protein binding has strong negative electrostatic and hydrophobicity, and PVDF filter protein binding is a new type of precision filtration membrane that can be used in liquid sterilization, particle removal filtration, and gas dehumidification, sterilization, and dust removal filtration. The biggest feature is very low protein adsorption, and the PTFE filter can also be used to filter gas.

PVDF membrane filters are commonly used for purification during sterilizing or clarifying procedures. Sterile PVDF filter membranes are often used for biological sterilization filtration after hydrophilic treatment.

As a filter manufacturer, Hawach provides PVDF filter membrane with OEM service, customized sizes. Provided a reasonable PVDF membrane price. Small orders are also welcomed.
