W. L. Gore & Associates (Gore) has added hydrophilic PTFE filters to its expanding 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 significant flow improvements while maintaining or increasing particle retention. This increased performance can provide a retention upgrade while maintaining system flow, reducing processing time.
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. They are well suited to filtration of aqueous and high-surface-tension liquids, especially where outgassing or bubbles are a concern. Applications include high-throughput filling, packaging and recirculation systems.
