W. L. Gore & Associates has added hydrophilic PTFE filters to its line of cartridge filters for bulk high-purity chemicals used in microelectronics manufacturing, including LCD, semiconductor, hard disk drive and photovoltaic. Gore Filters for High-Purity Chemical Processors can be used as drop-in replacements for existing filters to achieve flow improvements while maintaining or increasing particle retention.
The new filters incorporate Gore’s proprietary high-flow hydrophilic PTFE (polytetrafluoroethylene) filtration media, which does not require IPA (isopropyl alcohol) pre-wetting and completely eliminates de-wetting issues in most applications.
