Product strengths
1. High hydrophilicity;
2. Fairly high poroxity, high throughput and long service life;
3. Superb chemical stability and high temperature resistance;
4. Fluid filtration with high surface tension, without requiring advanced wetting.
Processing
The filtration materials are produced by laminating ePTFE micro pore membrane with PP non-woven fabrics with
high temperature bonding technology. After post treatment, they become perpetually hydrophilic.
The reinforcements are easily folded with high chemical compatibility.
Typical Applications
1. Clarify, sterilize and filter liquid strong oxidants;
2. Clarify, sterilize and filter highly corrosive liquids;
3. Clarify, sterilize and filter highly protic organic solvents;
ePTFE micropore filter membrane and various ePTFE compound materials have been widely applied in different fields, including electronics, micro-electronics, medicine, liquor-making, food industry, biological, engineering, petroleum chemistry, industrial wastewater treatment, seawater pretreatment and laboratories.
