Considering the chemicals &#; if any &#; in which the sintered porous plastic component will come into contact with is another key consideration to make when selecting your porous material. Below is a table showing the compatibility of typically used chemicals with our most common sintered porous plastics.

Sintered porous plastics can be manufactured using a variety of materials which can be selected as part of the initial design and engineering process. As your partner in innovation, Porex can provide expertise and guidance on material selection based on the pore size, pore volume, operating temperature, chemical compatibility, and additive compatibility desired. These material options include:

Sintered Polyethylene (PE)
This is the most commonly used material with a large range of pore sizes available (5 to 250 microns). It is a strong, lightweight thermoplastic that can withstand more process variation than other materials.

Sintered Polypropylene (PP)
For strong applications where rigid structure and a large pore size is desired, PP thermoplastic material is an excellent option. It shares many of the same chemical and additive compatibilities as PE material.

Sintered Polytetrafluoroethylene (PTFE)
For applications in need of ultra-hydrophobicity, high temperature tolerances, high chemical resistance, and excellent robustness, sintered PTFE is a perfect choice. It is 100% pure, free of PFOA and can filter particles as small at 0.1 micron using depth filtration while resisting fluid ingress.

Sintered Polyvinyllidene Flouride (PVDF)
For applications where your device is subjected to oxidizing agents or solvents, sintered PVDF is a great option. It is a low-weight, highly pure thermoplastic that is durable with a strong resistance to solvents, acids, and bases.

While these four materials are most common, there are other options available including nylon (N6), ethyl vinyl acetate (EVA), polycaronate (PC), and elastomers among others. Working closely with your application engineering team, we can define your specifications and applicational requirements to select a material that is best for you.

Sintered PE (Polyethylene) filter is a type of filter made by sintering (heating without melting) small particles of polyethylene under high pressure to create a porous structure. The resulting filter is a rigid, durable material with a high degree of filtration efficiency.

Sintered PE filters are commonly used in applications where high levels of filtration are required, such as in the pharmaceutical, chemical, and food industries. They are also used in water treatment and air purification systems. Some of the advantages of sintered PE filters include:

High filtration efficiency: Sintered PE filters can effectively remove particles and contaminants down to very small sizes, making them suitable for a wide range of applications.

Durable and long-lasting: Sintered PE filters are resistant to chemical and thermal degradation, and can withstand high temperatures and pressures.

Easy to clean: Sintered PE filters can be easily cleaned and sterilized, making them suitable for use in applications where hygiene is critical.

Customizable: Sintered PE filters can be made in a variety of sizes and shapes to suit different applications.

Some of the drawbacks of sintered PE filters include their relatively high cost compared to other types of filters and their limited ability to remove dissolved contaminants. Please us  for your requirements.
