PVDF membrane filter has a 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. PVDF filter have stronger corrosion resistance than 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.
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. PVDF membrane filter’s biggest feature is very low protein adsorption, and the hydrophobic membrane filter can also be used to filter gas. PVDF filter is commonly used for purification during sterilizing or clarifying procedures. Sterile PVDF filter membrane are often used for biological sterilization filtration after hydrophilic treatment.
PVDF membrane, has excellent chemical compatibility, including corrosion resistance, oxidation resistance, and heat resistance. Its broad chemical compatibility allows the PVDF filter to accommodate a wide range of applications especially those requiring a high flow rate. The flow rate of the PVDF filter is lower than the PES membrane. Hawach provides PVDF filter membrane with OEM service, customized sizes. PVDF filter manufacturers provided a reasonable PVDF membrane price. Small orders are also welcomed.
Advantage of PVDF Membrane
PVDF membrane protein binding passed ISO 9001 certified PVDF filter membrane has a high filtration speed Reasonable PVDF membrane price Raw materials of PVDF membrane protein binding are imported from Germany or the USA, so they have a high-quality membrane. Manufactured in the cleaning room, which ensures no impurities being introduced during the manufacturing process.
