Filtration & Energy
Enhancing the performance of filtration media.
P2i’s patented technology increases the hydrophobicity (water repellency) and oleophobicity (oil repellency) of filtration media to the highest levels. Surface energies as low as 7 mN/m can be achieved, giving repellency up to oil-9 on the AATCC 118-2012 scale.
The nano-coating has no effect on pore size, delivering superior repellency whilst maintaining air-flow. This maximises the lifetime of the filter and minimises pressure drop due to absorbed liquids.
As the technology is applicable to any filter media it offers new opportunities by widening the selection of materials available. For example, a lower cost or higher permeability material treated with P2i’s technology can be used instead of ePTFE for applications that require high levels of water repellency.
Furthermore, the performance and applicability of naturally water repellent materials such as polypropylene or PTFE can be enhanced further by P2i’s technology. Increasing the levels of oil and alcohol repellency allows their use in the most demanding environments such as automotive, industrial, gas turbine, and pharmaceutical product protection.
The P2i nano-coating is deposited via a vacuum plasma deposition process, ensuring the highest levels of process repeatability and control. The sealed, low pressure, processing chamber ensures an environmentally clean process with minimal energy usage and emissions. A variety of machine options are available allowing processing of media in roll or sheet format or, alternatively, processing of the complete filter assembly.
