PTFE is a thin membrane with highly porous films that act like 100% retentive membranes. However, there are new designs of PTFEs that allow water to pass through them. PTFE hydrophobic & filter China Manufacturers boast of making such PTFE products. This post discusses the difference between PTFE hydrophobic and hydrophilic filters.
What is the difference between hydrophobic and hydrophilic filters?
The differences between hydrophobic and hydrophilic filters mainly lie in the areas in which they are applied. Below are some of the primary differences between these two forms of filters;
1. Hydrophilic filters
The term hydrophilic refers to a material that is water-loving or attractive to water. For this reason, hydrophilic filters are often used in liquid filtration processes. The nature of these filters allows for polar liquids, such as water to interact better. The efficiency in interaction helps maximize the filtration process. Hydrophilic filters are also commonly applied in the medical industry. In this sector, the filters are used to enhance the process of bacteria removal from aqueous intravenous solutions, like Saline solutions.
2. Hydrophobic filters
Contrary to hydrophilic filters, hydrophobic filters are made using water-repelling materials. This is because the molecules in hydrophobic filters are designed to converge in water. For this reason, these filters are primarily used in gas filtration processes.
Hydrophobic filters allow for non-polar fluids, such as air, to interact better while preventing fluids, such as water, from getting through them. It is also worth mentioning that hydrophobic filters are commonly applied in gas vent functions. These functions occur within medical devices.
Here, the hydrophobic filters allow you to vent out gases, like air, while retaining water-based fluids that are important for the treatment of patients. In some liquid filtration processes, hydrophilic membranes can be used. This is because the membranes will wet out when exposed to lower density liquids and water surface tensions. Doing this helps prevent performance issues and various forms of liquid contaminations in the filtration process.
How to find the best PTFE hydrophobic and hydrophilic filters
When choosing the best place to purchase these two types of filters, it would help to consider the following factors;
The reputation of the seller or manufacturer is one of the first things you must consider. This is the only way to protect yourself from fraudulent companies and manufacturers. You can assess the reputation of a manufacturer by looking at its customer reviews.
2. Experience and expertise
It would also help to consider the expertise and experience of the company. You can do this by looking into former clients that the company has worked with and the kind of employees that provide services. It would be wise to hire a company with experienced workers.
It would also be wise to hire a company that offers a wide array of products. This way, you have numerous options from which to choose.
