the above data on initial bubble pressure and pure water flux is typical, the thickness is dependent on base materials
Product strengths
Compared with PVDF filter membrane, ePTFE micro-pore membranes have more uniform PTFE pores with
higher poroxity and higher water flux. In addition, the surface friction coefficient of ePTFE is intrinsically extremely
low, so MBR membrane elements made of ePTFE are more contamination resistant. Conventional PVDF
membranes produce much high-concentration refractory wastewater during their preparation.
This is also a major bottleneck that hinders promotion of PVDF membranes. PTFEmembranes are produced with
the most advanced dual-direction stretching and pore formation technologies. Their production process is more
environment-friendly, so PTFE membranes of higher market value for application.
Processing
The filtration materials are produced by laminating ePTFE micro pore membrane with PET with
high temperature bonding technology. The laminated membranes of reinforcements are quite flat and corrosion
resistant with high mechanical strength.
