PTFE Membranes, as a kind of filtration microporous membrane, has been widely used in many fields due to its unique filtration characteristics. It has small pore size and dense quality. The filter material can filter ultrafine dust, with good filtering effect and high economic benefit. Here’s a detailed description of its related content to let you know more about it:
About PTFE Membrane Filters：
Hawach’s PTFE membrane is a highly efficient microporous membrane made of naturally hydrophobic polytetrafluoroethylene material. It has low protein adsorption and good chemical compatibility.
It is manufactured in a Class 100,000 clean room without the use of adhesive additives. Through the control of micropores in the manufacturing process, the filter membrane can also ensure high retention rate filtration under high flux conditions. It can effectively capture some solids and colloids in colloids or liquids, and meet very high requirements for gas and solvent filtration. The safe workmanship and skilled processing of the factory make it also do a good job in moisture-proof and breathable.
In addition to the commonly used 0.22μm and 0.45μm pore sizes of PTFE Membrane Filters, 0.1μm, 1.0μm, 3.0μm, 5.0μm, and 10μm are also put into production and provided to customers with different needs.
Non-absorbent PTFE membranes are available in hydrophobic versions as well as treated hydrophilic membranes.
The chemical stability and inertness of PTFE make it chemically resistant and resistant to strong acids, strong alkalis, and many other highly corrosive media. It is resistant to most acids, bases and highly chemically aggressive organic solvents, aqueous solutions and gases. It can be used to filter almost all chemically active samples and complete the purification of these chemicals.
The filter membrane made of PTFE has a high melting point, good thermal stability, does not fall off at high temperature, is very resistant to high temperature, and is also resistant to climate change. It also has electrical resistance and oxidation resistance. A variety of sterilization methods are feasible for it. Such characteristics make it suitable for high temperature liquid filtration.
PTFE microporous membrane has high flow rate and high flow rate. And it has high filtration precision and strong solid retention.
Applications of PTFE Membranes：
Due to its chemical properties, it can be applied to the filtration of strong chemically corrosive organic solvents and strong acid solvents.
It is used for filtration of strong acid and strong alkali solutions, sterilization and turbidity filtration of organic solvents, sterilization and filtration of medicinal liquids, high temperature liquid filtration and other environments where filter materials are not competent.
Its high-efficiency filtration capacity and hydrophobicity make it also suitable for atmospheric smoke sampling, environmental testing, and gas filtration such as steam.
Widely used in chemical industry, power generation, waste incineration and other industrial flue gas filtration, as well as pharmaceutical, environmental protection, food, beverage and other industries.
In the sterile separation and filtration in the fields of biomedicine and bioengineering, PTFE microporous membranes are more and more widely used due to their advantages of high efficiency, energy saving, simplicity, and no secondary pollution.
