Description
Introduction
PVDF hydrophobic membranes has trong hydrophobilcity, high temperature capabilities and good heat endurance and chemical stability. PVDF hydrophobic membranes can be prepared to exhibit high efficiency for particle removal. PVDF has a low critical surface energy, PVDF membranes will not wet with aqueous fluids. PVDF hydrophobic membrane can ensure gas pass through smoothly, even when the differential pressure is very low. It holds the opposite capability against PVDF hydrophilic membrane.
Fetures

- Different pore size for option
- Natural hydrophobic
- High temperature capabilities
Application
- Solvent filtration
- Sterile filtration
- Gas filtration
- Pharmaceutical filtration
