Porex offers special composite materials to enhance the performance capabilities of porous plastic including end carbon loading of up to 40% by weight for potable water applications; ion exchange media for separation applications; color-coding; self-sealing agents to seal off porous material in contact with liquids or aerosols; and surfactant for hydrophilicity among others.

POREX Porous Plastics have been used for years in various bacteria barrier applications. Porex maintains documented test results that support the use of specific materials in applications requiring bacteria filtration efficiencies at or above 99.97%. As is always the case, these test results are specific to a test protocol whereby volumetric airflow, sample size, particulate type, and upstream particulate concentrations level are specified. The documented test results are also associated with a certain pore size/material thickness combination produced by Porex. Nonetheless, Porex's material has been used for years in medical devices with a variety of sterility requirements.

Porex does offer a solution for steam, ETO and/or gamma sterilization methods. Most of Porex's materials are suitable for any of the methods with a few exceptions. Porex's polyethylene materials can be used in steam sterilization applications by carefully noting the material's softening point and melting point. Porex's PP/PTFE/PVDF might be preferred in steam sterilization applications given their higher melt points. PTFE and PVDF are not recommended for use with any gamma sterilization process.
