PTFE Filter membrane
ptfe without support layer and PP as the supporting material of the composite hydrophilic membrane, due to its strong hydrophilicity and chemical compatibility, it can be widely used to filter various aqueous solutions, such as: strong acid, strong alkali, etc.
Product Characteristics
1.Strongly hydrophilic
2.Extremely good chemical compatibility,compatible with almost all acids, bases and solvents.
3.Excellent thermal resistance
4.Temperature resistance
5.Strong acid and alkali resistance
6.High particle retention and low solubility
8.High flow rate
9.Two types: hydrophobic and hydrophilic
Product Applications
1.sterile filtration of organic solvents, mixed solvents, acids or bases and strong oxidizing solutions
2.Filtration for aqueous solution
3. Filtering gases,including humidified air
4.Phase separations
5.Sterilize gases,vent gas from aqueous solutions
6.Air dust removal and gas ultra-cleaning filtration and particle removal in high-temperature or high-corrosion air.
