Description

Description of Hydrophilic PTFE Membrane Filters

With its filter media as hydrophilic PTFE, Hydrophilic membranes filters can help users reduce costs by eliminating the need for expensive pre-wetting in the applications that require the superior temperature, chemical resistance, and low extractors of PTFE membrane. Its bubble points (0.22μm, 0.45μm) are above or equals 0.1MPa and 0.06MPa respectively, with its diameter ranging from 13mm, 25mm, 47mm to 90mm, 142mm, 293mm. Its pore size are 0.22μm, 0.45μm and chemical compatibilities are superior to aqueous, organic solvents and mixed solvents. Hydrophilic PTFE membrane filters are the strongest membrane filters for strong acid, alcohol and so on. Our company has full range of products, diameters and pore size can be customized, OEM services are available as well.

Advantage of Hydrophilic PTFE Membrane Filters

Hydrophilic PTFE Membrane Filters of our company have been approved by ISO9001 and all are imported from Germany and US to ensure high quality. The filters are manufactured in 100,000 class cleaning room with various sizes, pore sizes and diameters available in supply for different applications. We also provide OEM service.

Features
